Guaifen-C and insomnia

I hve been taking Guaifen since Friday. By Sunday, I have experienced severe nausea, sleeplessness, headaches, hot flashes, dizziness, stomach pain, complete loss of appetite, shaking and increased heartbeat. If the side effects of the cure are worse than the sinus infection, why put this on the market?!

Have had insomnia for 3 days on this med, after specifically telling the MD (not my regular doctor) that I had trouble with pseudoephedrine. My heart rate was very rapid and irregular. I am also an athelete, and drink tons of water. This medication wasn't in my PDR, so thanks to this web site I have found what the culpret is, and it isn't menapause!!!!

I've taken this medication a number of times and the only real side effects I've noticed are the upset stomach if I haven't eaten or haven't consumed enough liquids as well as the sleeplessness. I toss and turn all night long and the slightest noise keeps me awake. Sometimes I think my hearing is hightened when I'm on this medication as the ticking of the clock seems abnormally loud. I will deal with the lack of sleep for a week or two if it means I'll get rid of the tremendous sinus pressure I feel.

I had no real problems at all. I felt a little funny the first time I took it (SLIGHTLY nauseated and dizzy), but I ate some food and drank some water and felt much better. I took it for about 4 days and it completely cleared my sinuses - the stuff coming out of my nose went from yellow to clear. I definitely avoided an infection. I would suggest only taking one pill in the morning - that prevents the sleeplessness. I also made sure I drank more water than usual. The bottom line is that it worked wonders, and there are side effects to ALL drugs. Sudafed would keep me up at night - that's why I stop taking it a few hours before going to bed.

It's 12:42 am and I finally decided to check the internet to see if anyone else taking this medicine was experiencing / experienced what I am. I cannot sleep. Having to clear my throat or cough all the time. Mouth is so dry that there are times I cannot swallow. It's awful. This medicine is going in the trash!

I took this drug for four days and had to stop taking it. On the third and fourth days I experienced vaginal spotting, sleeplessness, nausea and extreme dizziness. On top of that, my inner-ear problem (which I took it for) felt no better than it did before taking this drug!

Dry mouth, trouble sleeping and feeling a little high in the day. Decided to take it once a day in the morning instead of twice a day because it did help my congestion.

I have had trouble sleeping. It did help sinus congestion. Then moved to chest congestion that did not have before

I stopped taking this medecine because the side effect were horrible; trouble sleeping, severe dizziness, nausea.
