I was an everyday drinker for a long time and would also "binge" on the weekends (drink a lot more than I would on the weekdays). The last time I had withdrawal symptoms they lasted less than a few days (the sweating, tremors, upset stomach, etc.), but the constant insomnia went on for WEEKS and I remain somewhat of an occasional insomniac. Having said that, being tired during the day is far better than being tired and hung over.
