I think the pains I get in my head is from the Ativan I've been on. I never had pains like this before taking it. I was taking .5 mg. three times a day and my doctor has asked me to cut out the mid-day dose. Do I ever notice a difference. I can't wait until bedtime when I can take my next dose. That is TERRIBLE! I can't believe how fast you can become addicted to this drug. I sure hope the Effexor kicks in quickly and works for me.
