Hockeydad,
Zoloft gives me headaches too. When I was on hydros I remember going to my doctor about depression and the zoloft not working anymore. (CC is right, they were totally non-effective, minus the major headaches they gave me)
I would really suggest some other kind of pain management. Have you been on the pain management forum down below yet?
Also, hydros caused me depression too. hang in there, there is hope! blessings, Sheila
