Along the knee question theme - do any of you Glucosamine/MSM users experience any stomach problems when you take it? I tried it for about a week and had to quit because my reflux and IBS got so bad.

Yes, try the powdered form for both MSM and Glucosamine from Innate Source. You will find them on the internet

I've been buying this stuff from them for 2 years now. I mix it with my honey/'applecider vinegar concoction in the morning, then wait 20minutes before eathing anything else. Drinking juice or water OK.
