I Have Been Taking Venalfaxin ER 37.5mg For 2 Months....

I have been taking venalfaxin ER 37.5mg for 2 months.... Prior to that I was taking Zoloft. I asked to switch due to menopause hot flashes that were very bad. In the last 2 weeks I have been experising several bouts of sweating, nausea, and vomiting. If I take the pill with food the nausea and vomiting have stopped. I am still having several bouts of the sweating. Do you have any recommendations to help ease the sweating?
