Biaxin and tetracycline

Abyone experience excess salivating?? I have all the above symptoms and they are horrible! I felt better before the prescription. I am on 1000 mg once and day, 2000 mg of Amoxicillin once a day and a Prilosec OTC 2x's a day. I'm taking what's called a Prevpac for a stomach bacteria called H Pylori. This has been a 2 year journey to figure out what was causing my GI issues! I had a period of about a month with no stomach issues, BUT, as soon as the Biaxin it started right back up within 20 mins! The taste in my mouth is making me sick to my stomach and I'm trying to decide if I should stop. I'm trying to hang in there because in the long run it will work in my favor, but this is only day #4 and I have 10 more to go! Any suggestions?!
