I have been on effexor for about 2 years...this is the second time around..the first time I gained so much weight I decided to get off the drug...but you have to get off very slowly..your doctor should prescribe a method to get off this drug...I got off with no problem....I started taking this drug again due to severe panic attacks and this drug seems to do the trick...yes when I skip a day or more I do get that zapping feeling in my head...but that goes away...just remember if you decide to get off the drug just do it very slowly.. Good Luck
