Guaifenex Sinus Headache, Drink Alot, Lack of Sleep, Desert
Posted over a year ago
Doctor told me to drink alot on this med. I've drank enough to refloat the ark and my mouth still feels like I've been in the desert. I haven't slept in 3 nights since I started taking it and I've had a terrible sinus headache.
I feel totally out of it - I don't know if it is from the med or the lack of sleep.
