I think many of the side effects mentioned here are a result of yeast overgrowth- which is a side effect of most antbiotics since they kill the natural flora in your intestines. I had to deal with this for years with all kinds of bad symptoms until I hit the right web site -- started taking probiotics and yeast killers -- my health improved almost overnight.
Am on Dox. now because a dermitologist got me infected with some kind of bad bacteria. Have had some of the head symptoms described but not all the other stuff because I have been taking probiotics and yeast killers the same time. there is plenty of info on the web re this. IF YOU REALLLY WANT TO IMPROVE YOUR HEALTH YOU SHOULD TRY INTESTINAL CLEANSING-- MADE ME FEEL 20 YEARS YOUNGER. NOT FOR THE WEAK- WILLED PERSON -- YOU MUST WANT TO FEEL BETTER BAD ENOUGH TO GO THRU IT BUT I KNOW IT WORKS LOOK UP ARISEANDSHINE.COM
