Nightly Drinking, a Withdrawal Seizure, and a Request for a Court Letter
Marcus, 38, is a self-referred forklift operator arrested for DWI three weeks ago with a BAC of 0.19. He drinks six to eight beers every night and has for about eight years. An ER visit 14 months ago is charted as alcohol withdrawal, with tremors and vomiting. He reports morning shakes, sweats, and poor sleep, and says he had a seizure once while “detoxing on my own,” though he cannot say when. His primary care provider started sertraline 50 mg five months ago for “anxiety.” PHQ-9 is 14, GAD-7 is 16, AUDIT-C is 11. He smokes cannabis nightly for sleep and denies it is a problem. He denies being an alcoholic, calls the arrest bad luck, and asks you to write a letter stating he is fit to keep driving. His wife reports two blackouts in the past month. He has a 9-year-old son and no health insurance.
1. What information do you need to decide whether his anxiety and depressive symptoms are substance-induced or independent, and how should the assessment be sequenced?

The whole case turns on timing, and the timeline is currently too vague to support any firm psychiatric diagnosis.
- Anchor every symptom to a date. Last drink, last cannabis use, onset of shakes and sweats, date of the seizure, date sertraline was started. DSM-5 substance-induced anxiety and depressive disorders require symptoms that develop during or within one month of intoxication or withdrawal and are not better explained by an independent disorder. Because he is still drinking nightly, nothing you diagnose today is stable.
- Do not diagnose through withdrawal. Withdrawal itself produces anxiety, insomnia, dysphoria, and tremor. Sertraline started five months ago may be treating a picture that was alcohol-driven all along, so coordinate with the prescriber rather than treating the scores as fixed.
- Re-administer the screens after abstinence. Repeat PHQ-9 and GAD-7 after roughly three to four weeks of abstinence and compare; a score that falls substantially points toward a substance-induced picture.
- Get collateral with a signed release. His wife can date the seizure and describe the blackouts, which speak directly to severity and to denial.
- Screen cannabis separately. Nightly use for sleep needs its own assessment and muddies the sleep and anxiety picture.
- Document provisional diagnoses such as “alcohol use disorder, severe; anxiety symptoms, substance-induced, to be reevaluated on a set date,” so the record does not lock in an error you will have to defend later.
2. How do you handle his request for a letter saying he is fit to drive?
Read the worked answer
Three different things are being bundled: a clinical question, a legal request, and a defense mechanism. Separate them out loud.
- Name the limit of your role. You are his treatment counselor, not a forensic evaluator, and you cannot certify fitness to operate a commercial vehicle. Say that plainly and early rather than hedging, because vagueness will be heard as a maybe.
- Explain what you can produce. With a signed release you can send a factual summary of attendance, engagement, and test results, and you can state that he is engaged in treatment. You cannot state a prognosis or an opinion about driving.
- Use the request as clinical material. Wanting the letter is sustain talk. Reflect it without arguing: he is facing losing a job he needs for his son, and a letter feels like the fastest fix. The righting reflex here (“you have a serious problem and a letter will not fix it”) will end the interview, not the drinking.
- Ask about his own worry. What would it mean for him if the seizures kept happening at work? Change talk is more likely to come from that than from a lecture.
- Watch the secondary gain pressure. He is asking you to collude in his denial. Decline the letter, keep the alliance, and document the request and your response.
3. Rate his ASAM dimensions and recommend a level of care, with your reasoning.

Match the level of care to the highest-risk dimension, and here Dimension 1 drives it.
- Dimension 1, withdrawal: high risk. Daily heavy drinking for eight years, morning shakes and sweats, a prior medically attended withdrawal, and a reported withdrawal seizure. Untreated alcohol withdrawal can progress to seizures roughly 24 to 48 hours after the last drink and delirium tremens at roughly 48 to 96 hours. He also has no insurance, which makes “go to the ER if it gets bad” an inadequate plan.
- Dimension 2, biomedical: moderate. No acute complaint, but he needs baseline labs and a medical evaluation before any outpatient withdrawal plan is credible.
- Dimension 3, psychiatric: moderate, provisional. Elevated scores, but they cannot be interpreted until he is abstinent and re-screened.
- Dimension 4, readiness: low. He denies the diagnosis and is asking for a letter to make the problem go away.
- Dimension 5, relapse potential: high. Daily use, minimal insight, and a safety-sensitive job at stake.
- Dimension 6, environment: mixed. A concerned spouse and a young son are supports, but the job and legal pressure are also stressors.
Recommendation: Level 3.2-W, clinically managed residential withdrawal management, moving to 3.7-W if nursing assessment shows he needs 24-hour medical monitoring, then step down to intensive outpatient. Write the rationale in the record, including the seizure history and the lack of insurance, so the referral is defensible.
