Hi, I have a few questions that I hope someone may be able to help me with. I suffer with fibromyalgia and SAD (seasonal affects disorder). Because of the antidepressant I was taking for the SAD, I have been having various problems, consitipation, diarrhea, urinary infection, weight gain. My primary dr. suggested I go slowly off of the effexor. I did this very slowly but because this is a very bad time of the year for me (less daylight) I started myself on 5htp 200mg at bedtime. I have been feeling very light headed and in a fog all day long. I also feel extremely fatigued. I hoped it would pass but so far it hasn't. I really felt good when I was on the effexor but is there any hope that using the 5htp will help me to get out of this fog and be able to think straight again? Is the dosage that I am taking high enough?
