I have done it, a shit load of times. It's not even close to healthy but I wouldn't say it makes me feel sober. It usually makes me feel absolutely shitfaced. The end result is usually lying in bed, the room is spinning but I can't fall asleep because I'm pumped full of energy drinks or drinking till like 6 or 7am for the same reasons. If I can't sleep I might as well carry on drinking.
