It's due to the amount of alcohol you're ingesting and how much time you're doing it in, you're talking about some very significant amounts here. Depending on how often you do this the withdrawal can be very intense.
Why do you feel the need to get a room and binge? I think that's what I would be more concerned with.

Both withdrawal and dehydration.
