Dr oz symptoms and conditions

Hello all,
I'm a 45-yr old Air Force Major (Male) recently diagnosed with asymptomatic chronic Atrial Fibrillation (As in I have it and was walking around not knowing it). When I went to see the cardiologist, my B.P. was only 120 / 74 (Which, until they changed the rules, used to be normal)and he puts me on Diovan 80mg once a day plus Coumadin 5mg. Well the Diovan almost made me faint and I had numbness in both arms, plus a funky rash, kind of like chicken pox showing up on my arms and thighs.
I went online and read horror stories of Diovan so I stopped taking it immediately (I had only taken four doses and never had any horrible symptoms until after I took the meds!). Then the Dr. put me on an Event Monitor and it showed I was indeed in A-fib all the time, plus at night, my heart was racing briefly to 200 a minute while I was sound asleep. So he puts me on Toprol XL 100mg once a day.
Immediately I had trouble sleeping (Which I never had before, ever!) with crazy dreams and tossing/turning. My B.P. dropped to 88/65 and my fibrillating heart rate was 64!!! I was so mad because I actually felt better before the meds. I found this site and saw what everyone was posting and immediately took myself off the Toprol XL.
The day after stopping the Toprol I had slight chest pains (Like angina or gas bubble) but they went away on their own. I slept fine the next night.
I'm having an Electro-Cardiversion done on the 21st July to see if I can stop the A-fib and get in normal rhythm. I know the Dr. is going to be mad at me for stopping the Diovan and Toprol, but I'm sorry, I'm convinced there is a better way to beat all this (Namely exercise and eating right). Being in the service means you have to be Mr. Physical and Mental "perfect" all the time. I cannot afford to be diagnosed with depression in my line of work! Thanks to all on this website and I wish you the best.
PS. for those who think I'm being ignorant of my medication, I have a nice fat insurance policy and Power of attorney for my wife and kid in the event I keel over!!! I may be medication intolerant but at least I took care of my family.

I've posted a few times. I suggested that we ask Dr. Oz who is on Oprah and has a radio program about any way to counter react the ADR's of this drug. Plus maybe he can warn some others the danger of this poison so they aren't harmed. His email is http://www.oprah.com/xm/email/xm_email_moz.jhtml

I've been on TOPROL-XL( 50 mg) for about 18 months now. Gained 25 lbs. Lack of interest (consistently) in getting much done. I had an aortic valve replacement 12 years ago and they were recently concerned about an enlargement of the aorta-so they wanted the Toprol to reduce the blood pressure further. Its keeping the pressure steady but not a huge decrease. When I discuss the side effects- they smile beningly. I'm having difficulty with digestive tract issues, also, which seem to be connected with weight gain. Other than fluuid retention- anybody know WHY this cuases weight gain? Anybody had any luck switching to other medications??
