I took this to try and help some rather chronic sinus congestion. I only took one or two doses (it was a few years ago), but became really ill. I have palpitations normally, so I didn't notice that. However, I was leeched of energy and ended up spending half the day vomiting or feeling like I had to. I was cold and clammy, which is extremely abnormal for me. According to my coworkers, I looked pretty darn bad. I somehow made the long drive home (I wouldn't recommend) and tried to sleep. Eventually I passed out for a good 8 hours, but still felt yucky the next day. Naturally, I haven't touched the stuff since. To be fair, these side effects are listed under the drug info (online), but who thinks they are going to be in the small percentage affected? Also, in response to an older post, it's NOT pseudoephedrine. It is the ingredient in mucinex and a decongestant similar to or found in the "new" crappy sudofed. I've been taking pseudoephedrine for years with no problems. Glad I found this! I thought I was the only one!
