I've been dx with Gerd and have been having a horrilbe time with it this past 12-6 months. I am going to the Gastroentrologist soon. I just happened to remember something about Glucosamine and nausea. One of my major sypmptoms is nausea and bloating. Do you think this is causing all my problem or at least a good part of it? I've been on 2 pills a day 1500/1200mg. one in the morning and one at night. I seem to be better at night so hadn't given this a thought. Tomorrow I'll stop it but it scares me. My knees are so much better since I've been taking it. (1 year)
