I am on three Effexor capsules per day (since 2001). They will have to pry them out of my cold hands to get them away from me. They helped me climb out of a deep well of crippling anxiety.
I am not crazy about SSRIs (Prozac, Paxil, Zoloft) because they seem to interfere with my sleep patterns. But other people have had good luck with them.
It's very important to get counseling along with the meds if at all possible. Research shows the two work much better hand in hand.
If at all possible it is best to go on them very slowly and go off them very slowly. Start with tablets and go up a quarter tab every few days. Then you can switch to capsules.
