It is interesting how this med is a love or hate. I agree there are no withdrawal issues with it and it can make you irritable at times and even increase your anxiety. The libido thing for me was increased! Curved appetite, only sides not crazy about, constipation once in awhile and a little harder to fall asleep for the first two weeks. I requested the Zoloft for my anxiety. The two together produces best results, no zombie. However my primary doc is very concerned with me taking Zoloft along with Wellbutrin. He worries it may set of mania in me, but so far 4 months it has not, but does make me feel really good sometimes.
