Venlafaxine/Effexor turned my VM into Classic migraines

Thank you so much for your input. My pills are like you describe, with 3 mini pills inside them. So I started at 12.5mg, and have increased by one mini pill each time, with a minimum of 5 weeks between each increase.
All my pain is either on the top of my head, like a pressure feeling, or all in my left ear and on the lhs of my head. For you, I take it you felt the pain was worth it for the benefits you saw otherwise? How long before you saw improvements in pain?
