That is not TMI! I have been on a lower dose of Effexor for 2 weeks now and I still have diarrhea, fatigue, panic, and extreme vertigo. I actually just tried to shower and almost passed out. Glad to hear that I’m not the only one who uncontrollably sobs for no apparent reason. Do your symptoms lessen after eating? I get very hungry but I can’t seem to eat and it makes me weak.
