Forties symptoms and conditions

I just started taking Toprol XL 50 mg about a week ago. I feel a little confused though on the doctor's judgment. I have a slow pulse (tends to run in the forties) from running a few miles a day and have mild hypotension. I was dizzy, lightheaded, fainted a few times, blurred vision, shortness of breath, chest palpitations and chest pain. My pulse would go from 35 to 170 just by standing and walking ten feet. The doctors determined I have what is known as POTS Disease, even though i suffered some of these symptoms lying down. Although the Toprol is helping with my palpitations and chest pain, it makes my resting heart rate and blood pressure even slower. Doesn't that seem dangerous, seeing as it's already low for even an athlete? My symptoms seem to be remaining the same besides that (which I guess is good seeing as Toprol can cause my symptoms, therefore I thought my dizziness, etc. may get worse). It's causing trouble sleeping, vomiting, cold feet and fingers.

I work at a computer all day. I have just begun taking Wellbutrin and I have noticed that my eyes seem to be getting more and more sensitive to the light on my screen. A couple days ago, I was looking at a paper and then back at the screen while I typed and, my eyes just went out of focus. It was like I was looking cross-eyed. There were two of everything and it made me really dizzy. I have had inner ear problems in the past and I don't know if the Wellbutrin is triggering them or what. I am not using alcohol or other medications other that Benadryl at night. Has anyone else experienced this? This is scary.

I have been on it for about 7 weeks now, I have the best Dr.I dont know what I would do with out her..I am transitioning from the Dilantin, been on that 25 years, now have ostiop........... ( Used to be a really good speller, maybe thats a forties thing!) in my hips and back. I started feeling really good, now having huge lapses of depression, Lonliness, eye sight which I hear very common, spotting different times of month, headache, dont know if its a side effect but each time I up my dosage things I think are becoming clearer, and cry a couple days, like to much information is flooding my mind. I Have bad dreams the kind that you can obviously analize, but wake up crying. Its a very lonely place to be, people think you will have a seizure thats why they avoid me ( I have been told) which I dont understand because Im taking more medicine and feeling better!
