Toprol-XL and healthy diet

I was weaned off 50 mg Toprol over an 8 day period (after having been on it for 4 years) and then had been off it completely for 10 days -- when my Dr. decided that what I was feeling could not POSSIBLY STILL be side effects from Toprol Withdrawal and so put me BACK on it at a lower dose (25 mg instead of 50 mg) - and 80 mg of Diovan (along with Prilosec OTC for acid reflux and a Hiatal hernia) - the Diovan made me so sick, I developed a bad cough and pains in my upper chest so I stopped that --- and low and behold after being back on the Toprol 25 mg for 2 days -- the severe chest tightness is BACK and worse than EVER -- it is horrible. I am a 33 year old woman with asthma (5'3 @ 135 pounds with no other health problems) -- my problem is without meds my B/P runs 140/110 (they say that it is genetic and that I do not work out and have a desk job - because I do not drink or smoke and I am not overweight, and I eat a very healthy diet) -- but the meds they want me take for it give me so many side effects I cannot STAND IT.. I don't know what to do -- I go back to my DR. Wed for a follow-up but cannot stand this chest tightness until then.......... Being 10 days off Toprol I was still have chest tightness and breathing difficulties -- but not as often and not as severe - so I thought maybe it just took a long time to get out of your system... My Dr. said I should have been feeling better after 3-5 days so that it could not possibly be the Toprol. I am at my WITS END and do not know where to turn or what to do.
