Toprol-XL and gp

I am a 45 year old black female. After the death of my father, I started experiencing blood pressure problems and headaches. I was diagnosed with obstructive sleep apnea 2 years ago. Not having bought a CPAP yet has contributed to a lot of the blood pressure and headache problems. But, my GP put me on Toprol in June '08. I am having difficulty sleeping.Every time I eat, I have severe gas and my chest is hurting off and on. There has got to be a better solution. I started exercising and using Isagenix (******). It is simply wonderful - I have lost weight and toxins. When I go to my doctor on tomorrow, I am going to ask him if I can get off of Toprol. I do not like the way this medication makes me feel.
