i feel no emotions while taking effexor. no anxiety, mind you, (which is what i was using it for---GAD.) so no anxiety is good, but is it good to not feel any sorrow, empathy, joy or happiness??? I feel like i am just going through the motions of life, not really living it. but if i don't take even 1 dose, the anxirty comes back. (but the other emotions come back too) i cry more if i miss a dose, and that used to worry me into thinking i am depressed....BUT it is normal to cry when you feel sorrow or empathy. and maybe the tears have to come flowing out as a form of release, because they were withheld for so long by the effexor. other possible side effects could be: insomnia; headaches, clenching teeth, biting cheek and tongue a lot, constipation and weight gain. (hard to know if these are side effects of effexor, or symptoms of fibromyalgia).
