Guaifenex and hot flashes

It's not 3:15 am, but I was still up at 3am this morning :-( I'm experiencing almost all of these symptoms as well. I've been unable to sleep since I started taking this a few days ago and I feel like my heart rate is thru the roof! Poor sleep patterns, hot flashes, increased heart rate, lack of ambition, axious and moodyness. I've had them all. I thought I was going crazy! Last night, I even thought I might be having an anxiety attack, which started me thinking that it might be this medication. Before I started taking this, I was so completely calm and relaxed, except for the cold. I'm so glad I found this website. Thanks.

It's 3:15 am, and like other posts, poor sleep patterns, hot flashes, increased heart rate, lack of ambition to work (almost depression). Am taking for blocked ear tube. I guess I'll look for another solution. Thanks for website and to each that posted!

I'm so glad that I logged onto this site - I have all of these side effects. After reading this, I immediately called my doctor for another medication and threw remaining pills away. I thought I was starting to lose my mind !!! Only took one tablet for three days and couldn't sleep starting with the first night. Next two nights I was completely restless with horrible leg cramps that last all day. Had extreme thirst during night, with hot flashes. It's absolutely the worst medication that I have ever taken. I will never take another medication without first checking this website for side effects. Thanks.

Unable to sleep, headache, loss of appetite, don't know if I'm having hot flashes or feeling is caused by Guaifenex. Called pharmacist after first sleepless night, was told to just take one pill in the morning and discontinue the second pill. Still not sleeping. Am stopping medication after three days.
