I've been on 6MP for almost 2 years. I get a few colds/flu things a year but nothing like you're describing. I don't find that I get sick any more than before being on it. I'm sorry your doctor is only concerned about
your colon, that's pretty much always been the case for me too with any doctor I've had. I'd be persistent in trying to get to the bottom of your ill feelings. Being in remission but feeling sick all the time must be horrible.
