I used to go to class all the time high when in college, but at the work I go to right now I just can't hang. I have to be on my toes, and my brain running a mile-a-minute as I take over 100 phone calls a day with all kinds of other projects in between. I tried it once, and couldn't even TALK straight! I blamed it on lack of sleep, but I'll never freakin do it again!
But what do you mean by "professional event," like where your peers/bosses will be? We went to a company picnic pretty blitzed, that was OK, but if you mean concerts, if it fits in certain crevices, it goes with me.
