Toprol-XL and birth control

I am a 41 yo woman in good health. I started Toprol xl about 3 years ago for a heart palp that would happen maybe once a day, and occasional racing heart beat. I did great for a long time on 25mg once a day. Then about 6 months back I was switched to generic due to insurance issues - they only want to pay for generic.

It took me a while to figure out what was happening, but several problems started happening over the last few months that I am sure were from this generic drug. Suddenly I was having vivid dreams - fish swimming on the ceiling, cats with heads 5x too big! Worse yet, over about 3 months I gained 20 pounds with no difference in diet. And I was getting more and more tired. I started looking into what could be causing these crazy effects - I was only on Toprol and birth control pills.... well, it was not the birth control!

So, I decided to wean myself from the Toprol. I decided I prefer a heart palp and occasional racing heart to this!! I gave myself a couple of weeks of lesser doses, then 5 days ago I stopped it altogether. I am having some horrid "rebound" or withdrawal effects! Numb/tingling hands and feet, headache and - surprise! High blood pressure! I never, ever took this med for HBP, and I have never had HBP! I always had a nice, low blood pressure, even when 9 months pregnant! Now it's running around 135/93 - I work in a medical office, so I got one of the nurses to check it on Tuesday...she sort of freaked! She said she has seen much higher, but mine is not normal. So we have been checking daily, and it's staying up there. I am so mad to think Toprol could have damaged my body in some way so that my blood pressure may not stay messed up for life. I have read online that the rebound effects can last up to a month, even with a fairly low dose like I was taking. Does anyone know if a month is about right? If my blood pressure keeps this high, I suppose I will have to seek treatment at some point. Ugh!

On the plus side, I don't feel so tired. No vivid dreams since I stopped the Toprol, and much better sleep! I feel "clearer" mentally. I just wish the tingling hands and feet would stop - and the high blood pressure!
