Toprol-XL and freaky

I've been taking toprol for over 3 weeks now for slightly fast heartrate. I've been experiencing headaches almost daily and a fuzzy (not with it in my head feeling) and my feet are cold alot, other than this, it's hepled me pretty much with the fast HB but I also experienced palps. before takinf the toprol, especially around that time of month, hoping it's hormonal and was told it probaby was, but the Toprol hasn't seemed to be helping that alot. I'm not real sure how I feel about the medication. I have another appt with my cardiologist on Monday the 21st of March. We'll see what she has to say. It's freaky putting crap like this in my body but a fast HB is creepier, but if I could get rid of the headaches, I think it would be fine.
