social anxiety has my life almost at a complete stop. I can't tell you how much I've missed from being too scared. It's so not worth it. I tried paxil a year ago, and it worked for about 4 months. But after a while, I felt like I was getting major withdrawals (ever heard of the zaps?) So Paxil was good, but not worth the side effects I felt when I missed a pill.
Xanax is nice. Because I've always had social anxiety, I drank. And nobody ever agrees with me but drinking made me a completely different guy. (not depressed one bit) I could pick up every girl I met at a party with a good buzz. I even use to take paxil and drink at the same time. SOMETHING REALLY not recommended. Well, because alcohol isn't good for your body, I tried to just take xanax, but a half hour later I was knocked out, ready for the nearest bed. IT made me so sleepy..
Basically to make a long story short I'm trying new meds.. But I hope you realize you can get through your wedding without a problem with the right medication. (and maybe talking to yourself in your head) Plus I'm sure looking at your beautiful new wife is going to be the best feeling. Good luck.
