I have been on Effexor for approximately 10 months to reduce stress and depression, and it has been successful thus far. However, I have two side effects that I hope someone can give me more information on.

1. Alcohol - after having a few drinks, I get the worst hangovers. I am extremely nauseaed, vomit, shivers, headache, etc. I know these are common hangover symptoms, but these last over 24 hours and are much worse than usual. Does effexor the cause of this, and should I avoid alcohol in the future?

2. Weight Gain - I noticed I gained around 10 lbs when I started the drug, and I cannot lose any weight even with dieting and regular exercise (I run daily). Any advice?

Thank you for your help!
