Hi everyone I'm new here so bare with me. I took Guifenesin for 12yrs, stopped taking it about 6 months ago. I don't feel worse or any better. I feel I have wasted a lot of money. I do believe it has helped many people it doesn't work for everybody I was not one of the lucky ones, but hey I'm very pleased that people out there are getting better.I have had it now since childhood and I'm now 60 its been apart of my life for what seems forever,as the docs keep telling live with it , it's easier said than done.I am really fed up with it at the moment I'm really suffering can't wait for my good days this weather is making matters worse it's like winter all over again for us .Anyone out there wanting to try guifenisen give it a go it may work for you. Gentle hugs.
