Hi Minnie M,I wanted to say hi because I also have IBS and recurring diverticulitis. In fact, my IBS started after a bad case of divertic. What antibiotic did you just take? I also have had symptoms of shakiness and trembling and leg weakness. Sometimes i think it's from being dehydrated. Try gatorade for this or Pedialyte, which I find is really effective for dehydration. Other times I feel that the gas, acid reflux, and general indigestion from the antibiotic and diarrhea affects my breathing. then breathing exercises help. I found a good breathing exercise in Andrew Weil's book Natural health Natural Medicine. It's listed as a relaxation technique. I have taken flagyl (with cipro)for divertic many times and now can't tolerate it any more. What do you take? Have you had this several times? I'm new to this site; would love to trade info.Rosie
