Toprol-XL and constant headaches

I've been taking Toprol XL for PVC's for about a year now. At first they also took away constant headaches, yeah!!! But as of late, i've noticed that I'm EXTREMELY fatigued all of the time, i've gained at least 10 pounds since taking this and my circulation is horrible in my hands and fingers. I still have the PVC's anyway. I went off the meds 3 days ago, without DR's ok and kind of feel dizzy and yucky, i have to go see the Doc tomorrow cuz he's miffed that i stopped taking it. Anyway...that's about it

I have been taking Toprol 50 mg daily for about six weeks. About 3 weeks ago, I started to be aware of a constant mild headache. This has progressed to a very troublesome aching in my head, face and neck, sometimes worsening with throbbing pain which keeps me awake at night. I am now weaning myself off Toprol, as it is causing me such misery as I have never before experienced such relentless pain and constant headaches.
