I'm not real sure what to do, do you have anyone with you 24/7 in case of emergency? I definitely understand hesitation about notifying Dr. may sound crazy to some, but like you said for those of us who finally find something that works and its just a temporary side effect,you just screwed yourself by telling the Dr. On the other hand we all know breathing is pretty important(just trying to get a smile) it's something you and someone else should monitor very closely. I wouldn't wait too long if it keeps up, and you never know the Dr. might just want to examine you, and if nothing too serious keep you on it. But like I said dont wait till it's too late. We all like hearing from you!! Keep us posted.
