Be careful on starting any new drug..see my last thread..side effects can occur from mixing pain meds and anti depressants...that up and down feeling can be one of them just from anti seizure and pain meds...make sure this doctor understands every drug your on and call your pharmacist first, tell them you were given samples and what your taking now...then and only then start a new drug...

On a personal note my mom was given effexor for depression after her hysterectomy...she had a bad reaction...many gynos love to give you anti depressants instead of hormone therapy when your going through the change...
