I did not take that med sat or today and am already feeling pretty much better. Fatigue is another side effect and I was tired. I figured it was only because I had not had food all day and was up vomiting and what not all night. Now I feel like a fog was lifted and I have my energy level back up. I am pretty sure its all from this med. Ofcourse my dr and I will figure that out. Lots of folks online saying this drug was no good for them. I guess not. I am not currently working at the moment but if I was there is no way I would have been able to go in like that. I still have a horse/sore throat the got worse today. Another listed side effect(of course throwing up a million times dont help). Thats one beta blocker that is not for me.
