Guaifen-C and pharmacist

I have taken the pill and it seems to work OK for me..... The pharmacist said that it would make me jittery, but it does the complete opposite. For the first half hour I do feel lightheaded and out of it... But then it puts me right to sleep for a good night's rest!

The doctor's office prescribed Guaifen for this inner ear ache. The pharmacist explained that this medication has a stimulant. Since I'm a heavy diet pepsi consumer, I didn't think that Guaifen would keep me awake. After two hours of sleep I awoke and can't go back to sleep. As prescribed, drinking a lot of water goes with the medication; the side effect is frequent trips to the bathroom. Now, its 6am and I wonder when I will sleep again.

I was prescribed Guaifen for nasal congestion along with Leviquin for pneumonia. I was told Guaifen might keep me up at night, so I started with just 1 tablet/day instead of 2 and took it twice a day on the weekend. Glad I did as the 1 did keep me awake as well as seem to make my mind race and gave me more dreams/nightmares than usual. On the medication, I wasn't tired but a person needs 6-8 hours of sleep every night, NOT 2 hours. Next time, I will read the side effects before I get my script filled, and call the dr or pharmacist if need be to discuss it further.
