I too have the sweating issue which also causes my body to quickly dehydrate and overheat. I am able to attend outdoor events but not without my trusty Camelbak filled with 70oz of an electrolyte drink. I also carry a bottle filled with the same drink just about everywhere else I go. I can't make it through the grocery store without it. I work in a rather warm environment and in a 3-hour shift i drink anywhere from 30oz to 70oz or more without using the bathroom. I keep my apartment around 68 degrees and sometimes still overheat. Heck, I even overheat in the snow.

I agree that this is certainly not a pleasant side effect. However, I have learned to cope as best I can because going back to how I was before my meds just is not an option for me.

My meds are:
Effexor XR 150mg, Prozac 40mg, Seroquel 200mg, Ativan 2mg, Adderall XR 40mg, and also other non-psychiatric meds.
