Guaifen-C and guaifen pse er

I've had ringing in my ears for a couple of years. Found out it was from sinus pressure. At times my vision would go blurry from ther extreme sinus pressure.
I have been taking Guaifen PSE ER for a couple of months. It has lessned the pain and actually stopped the ringing once. Taking lots of water is very important. It is hard some times to handle the irritability, but harder to handle the feeling your head is about to explode, which it has completely handled. I just started noticing the problem with urination, which I do lot of with all the water I'm drinking. I wake up at night with post nasal drip and lots of phlem which I am happy to see go. No way I will take this for years as some have done. If it comes down to that, I'll call roto router to clean it out.
Does anyone know of a natural cure for sinus trouble?

Guaifen PSE ER, Has anyone experienced extreme limb achiness with this med?

I believe this medication, Guaifen PSE ER, may have been a factor with problems in my left eye. Was on it for a week and began to see light flashes, and then floaters. Had to see my ophthalmologist immediately. It may have raised my blood pressure enough to cause this problem. Will not use it again!

I was prescribed Guaifen Pse Er for a "stuffy" ear. I am on day 4 - experienced extreme difficulty in urinating the past two days. After reading this site, understand that this is a side effect. Going off med and calling my ENT to get correct medcine. This web site is great.

I was prescribed Guaifen PSE ER Tabs for my ears and also an antibiotic for my sore throat. I have noticed a mild loss of appetite. I also flew to Montana for a wedding and my ears wouldnt unpop after we landed, they are still acting a little funny after 4 days. I was instructed NOT to take before bed, but twice daily earlier in the day because if does cause problems when trying to fall asleep.

I was perscribed Guaifen PSE ER Tablets and an antibiotic for a bad cold. This is my 5th night taking it... and for the past few nights I haven't been able to sleep at all! Last night I couldn't get to sleep until 3:30am, and I got up at 8am, and now its 1:20am and I am not tired.
I am not taking anymore!
