Guaifen-C and sinuses

I never take more than half a pill a day when my sinuses were unbearable, and I never had any problem. I drink lots of water and never take it after 2PM and was fine.

I had no real problems at all. I felt a little funny the first time I took it (SLIGHTLY nauseated and dizzy), but I ate some food and drank some water and felt much better. I took it for about 4 days and it completely cleared my sinuses - the stuff coming out of my nose went from yellow to clear. I definitely avoided an infection. I would suggest only taking one pill in the morning - that prevents the sleeplessness. I also made sure I drank more water than usual. The bottom line is that it worked wonders, and there are side effects to ALL drugs. Sudafed would keep me up at night - that's why I stop taking it a few hours before going to bed.

The guaifen is an expectorant, so of course it will make you cough!! That's what an expectorant does!! It loosens the phlegm so you can cough it up and out (unless you just WANT to swallow it). Also a bronchodilator which helps breathing.

The loss of appetite, not being able to sleep is caused by the PSE part of this Rx--PSE being pseudoephedrine which acts like speed for a lot of people.

Makes my nose a little dry but drains my sinuses and opens up my lungs, which is why I'm taking it!!
