I was taking 500mgs of Neurontin for about 5 months. I am very sensitive to meds, so my psych decided I should "try" this for my anxiety disorder. I was wonderful until my hair started to fall out..and I mean FALL OUT. I also gained about 8 lbs--facial swelling also. Well, if I thought that was bad, I am into 5 weeks of withdrawal and I have NEVER been through anything like it. My anxiety is so bad that I am never at peace unless I take prescribed tranquilizers..1and 1/2 mgs of clonazepam and .75mgs of xanax. My digestive tract is completely off- balance..horrible indigestion. Sometimes I feel that my nerve endings are exposed. My knee joints ache also. I have never felt more miserable in my life. My psych is on sabbatical and never returned my emergency calls even though he is still legally my psych with no backup psych. Please tell me, are these side effects permanent? I can take it if it's temporary....
