Guaifen-C and flu

I was prescribed this Guaifen semi-horse pill on 1/24/05 for the flu, I haven't slept more than 5 hours during the last 36 hours, I sweat like a wet towel, I had to change my bed, my clothes because of the sweat and I feel like and going out of my head. My doc didn't mentioned any after effects.

I was up all night with my heart racing and I felt like horrible. And when I did doze off I would have the worst nightmares. It made my body hurt like I had the flu and the cotton mouth is horrible. I took one pill last night before bed and it is now 12:25pm next day and still feel like I have the flu. This didn't help with my sinus congestion either I had post nasal drip all night and still now. This is a horrible medicine!!

i have never felt so sick to my stomach over a precription before. i was given to take for the cold bug and i have been sick to my stomach, dizzy, clammy, and i feel like i have the flu. Aweful!
