I'm a 30 yr old healthy male. I went to the ER, and then the Dr., about 4 weeks ago after waking up with intense pain in the veins of my right arm and having pounding palps. I had just been told some extremely stressful news the night before, so I was pretty sure this was blood pressure & stress related. ... EKG showed Wolf-Parkinson-White syndrome, so that's what the Dr's assumed was the problem. I never knew what it was called, but I've had my heart race due to WPW many times since I was a young child .. this did not seem to be related. This was just pounding. The cardiologist put me on 50mg of Toprol XL daily to control the WPW - even though that wasn't acting up. I left confused. Pharmacy issued generic Metoprolol Succinate mfg. by Sandoz. I didn't want to be on meds, so I didn't take it for the first few days, hoping that I would return to normal. After all, I just woke up with this all of the sudden.. I had been fine the day before. Palps continued, though, so eventually I relented and started taking the meds. The first two or three weeks were filled with ups and downs. Exhaustion, palpitations and anxiety would come and go. This past weekend things got really bad. I began having anxiety attacks -- I think that's what it was, I'd never had one before -- and my vision was totally screwed up. I couldn't focus on anything and was sensitive to some lighting. Black text on a bright white screen (lcd monitor) was especially hard to read. I was completely in a dazed & confused state. Loud noises and crowds were bothering me... which was awful, considering it was my best friend's wedding. Also had headaches, lightheadedness & loss of appetite. These side effects came and went on Friday & Saturday and were pretty constant on Sunday & Monday. I decided to quit Toprol cold-turkey on Sunday. I have been 2 days without. I have used L-Theamine to reduce stress and keep my blood pressure steady. It seems to be working. I also began taking CoQ10 today after reading some good things about it here. My vision & mental focus is beginning to improve after 3 days of disabilitating problems. Anxiety has also improved. I even attempted to "get back to normal" at work today, but had to leave after only an hour of strenuous exercise in the heat. Vision problems returned, anxiety set in. It's like riding a really freaking scary roller coaster, except with a legitimate fear that this thing might kill you. I will update this as time goes by, to let you all know how things worked out for me. I'm really hoping to be mostly back to normal in another day or two, since I haven't been on for very long. Hopefully this will be of help to someone in the future. Damn, I Wish I had never gotten on this stuff.
