effexor xr was my worst.i had a bad experience with it.and will never take it again.i had trouble with my vision and when i awoke the next morning i had a hard time breatheing and was dizzy..lexapro was helping but made me to tired..now i am on fluxatine which is the substitute for prozac...i like it but it also has its side effects but they r tolerable so far..i only had a few headaches and some anxoiusness.other than that it is helping so far..
