Guaifenex and vomiting

I started having severe cold symptoms on Weds night... finally decided enough was enough and went to the walk in clinic for a really bad sore throat. Was told the sore throat was because of the nasal drip I was having... I got prescribed Guaifenex and I've been sick since half an hour after taking the meds. I tried waking early, sleeping all day, eating all day even though I was NOT hungry... last night I spent 4 hours sitting on the tub across from the toilet having stomach convulsions and puking up small amounts of red stuff... now I realise it was blood. I haven't slept since Friday night either... the most I can get in is a 20 minute nap. I'm actually lucky because the sticker on the pill bottle says take twice daily and I've only been taking it once a day and feeling like this. I was driving down a SMOOTH HIGHWAY (4 lanes!) today and got so carsick I had to pull over on and vomit... I also have had NO VOICE for 2 days... nothing more frustrating! I have to say my sore throat is pretty much gone, whats left is from me straining to yell at the dog to come in... this drug made me MISERABLE... I am going back tomorrow to give that doctor a talking to... and I expect a drug that isn't going to make me think I'm DIEING... (I actually considered going to the hospital because I felt I was having a seizure).

My husband took this for 3 or 4 days. He couldn't sleep, had terrible leg cramps, mild vomiting, mood swings, he felt hot and sweaty, couldn't get enough to drink but didn't want anything to eat. I had also taken this medication last fall, but felt so lousy I quit after 2 days. I can't remember the specifics; I just felt horrible. He decided to quit taking this medication this morning, and he actually feels like a human again tonight. We will *never* take this stuff again.

Taking this with Biaxin XL made me VERY ILL. It began with a major migrain and then Vomiting non stop for 2 1/2 days with burning feeling in lower abdoman.I was being treated for sinusitis. I will never take this medication again.

After 1 1/2 pills I became excessively hot and vomited violently for more than an hour. After vomiting stopped I bcame cold. I felt blotted and gasy. It has left me feeling very weak. It also affected my appitite. BAD STUFF!

The pill caused me to vomit, i felt stoned, weak, tired but couldnt sleep, when i was able to sleep i would wake up in pools of sweat

The first time this medication was prescribed for me I could not sleep. It makes me cough all the time, and at night it makes me cough until I vomit. The second time the doctor prescribed a different dosage/medication but it was still Guaifenex. Same results. I have called to request a change in prescription.
