Mucinex - starting guaifenesin for fibro?

Mucinex comes in several forms packaged with other drugs. I do think it's worth trying a guaifenesin only product. I used it maybe 20 years ago and it helped. Thank you for reminding me to try it again.
I don't remember too much about it other than it pulls some substance out of your system. The increase of this substance in the blood could cause one to feel worse. I also remember having to brush my teeth more often. Detoxing with more fluids, fiber and probiotics may be helpful. Detoxing herbs that support the liver are milk whistle, Reishi mushroom, schisandra, dandelion, turmeric, and artichoke.
Please let us know what happens with the guafenisin. It appears to be a safer medication than others that are recommended.
