When do alcohol withdrawal symptoms typically begin after cessation?

• A. Within minutes after cessation.
• B. Within 6-24 hours after last drink.
• C. Within 72 hours after last drink.
• D. After one week.

Answer: (B)

The main idea is the typical timing of alcohol withdrawal onset after stopping drinking. When someone who has been drinking heavily stops, the brain shifts from a sedated state to a rebound hyperactive state. This change usually shows up first as symptoms that begin 6 to 24 hours after the last drink. Early signs can include tremors, anxiety, sweating, and nausea, and the body’s autonomic nervous system becomes more active as alcohol leaves the system.

Starting within 6–24 hours also fits with what you see clinically, because by about 24–48 hours the withdrawal can intensify and, in some cases, seizures can occur, with more severe delirium potentially developing a bit later. Saying it begins within minutes doesn’t fit, since withdrawal isn’t felt until the alcohol is cleared enough to unmask hyperexcitability. Waiting until after a week misses the common early onset window and would be much later than when withdrawal commonly starts. So, the most accurate timing is 6 to 24 hours after the last drink.
