Bupropion
"I just recently began having panic attacks and becoming depressed (within the last 3 months). When I went to my doctor he put me on Lexapro.  Horrible! I took it for 3 days and it made me feel like a zombie. He then put me on Buproprion XL and I feel like my old self again.  It took about 4 weeks to take full effect, but, if you hang in there, it is a great thing.  I have had some side effects like dry mouth, trouble sleeping at night and really strange dreams, but, the longer I am on it the lesser the side effects are becoming.  I still have to take the occasional Xanax, but all around I feel great. I am so thankful that I didn't have to go through all the other depression medications to find the right one!"
