Effexor XR and sadness

i was prescribed effexor xr by the mayo clinic in mn. while living there for a year. i had been on three other antidepressants before and this one has really given me a sense of peace. i have had to go off of a lot of medicines and quite smoking cold turkey so maybe i have a stronger tolerance. i haven't had one bad side effect. in fact, i have probably been healthier since it kicked in two years ago due to my mood and mind being in a better state. don't get me wrong, i still have low times but not any lower than the person who doesn't suffer depression. it also helps with anxiety but i do take another med for that called klonopin 2mg. i think it takes awhile for the person to find whats right for them. i suffered horribly through wellbutrin, thought my head was going to blow off when i didn't feel bugs crawling around. prozac put weight on me but helped, just made me a little to jittery and the other one i took was zoloft. i didn't have any side effects with that just didn't seem to keep me above a sadness level i needed so that is when they switched me to effexor. please just know there is help for all and bravo to those who can go without but i don't want to be sad and unhappy ever again to the degree of not wanting to get out of bed.
