I have was on Prozac and Xanex for about 8 ys for Panic Attacks... My Dr decided I had been on it for a long time & switched me to Effexor, after being on it for about 8 ys I very gradually went off of it & then started having ache & pains in legs, feet, arms & hands so they told me to go back on the Effexor & see what happens I did & the ache & pain all went away, now with a different Dr's help I am weaning off Effexor again and I'm having a tough time, crying, feeling inferior, etc. Is there anyone else having a similar problem?
