Toprol-XL and give it time

Today is my ninth day coming off Toprol (had been on 25 mg for 2 1/2 years, then 50mg for 1 1/2 years) - today is the first day that the Dr. does not want me to take any Toprol. It has been SO DIFFICULT... Extreme chest tightness, shortness of breath, heart palpitations, headaches. She has me switching over to Diovan (80 mg) which I have been taking for 7 days now. I want to believe that everything I am feeling is from the Toprol Withdrawal and not NEW side effects from the Diovan - but I am scared. I feel really awful, I have no energy. I lay in bed waiting for the bad feelings to pass and they do not. I have lost 7 pounds in the past (2) weeks. Not sure if it is from going off the Toprol - or just not feeling that well. This website has been my only source of sanity and peace. Anyone else gone off this and can tell me what to expect? THANK YOU!

I started taking 25mg about a few days ago, now I'm experiencing blurred and double vision along with a 'fog-like' haze around my brain. I'm almost sure. After reading through these posts I'm pretty sure I'm not gonna "give it time to work" as the doc suggested.
