Zoloft and alertness

I've been taking zoloft for about 4 days and I've felt almost like I was on meth for 2 of the days, and I lost a lot of my water weight(drink a lot of water with this) , sweating a lot, and just kinda tripped out. The mood change is crazy, I felt goofy out of the blue for no reason. I've been clenching my jaw and that guy was right, a little high grade marijuana goes a long way! Waking up suddenly but falling right back asleep, and kind of an alertness to everything.
Hopefully I level out, I have bad social anxiety which causes me to studder but this seems to be helping a little so far.
Does anybody know about drinking with this, is it safe to have a couple beers or do I have to stick to iced tea?
