My son has been on 6PM for several years. So far, so good. He is now in college and eats everything except Mexican & chinese and (drinks some wine - not supposed to).
I don't think he will go on this forum, but if you email me I will have him send a reply.
He was diagnosed at 14-15 and is now 20.
Before allowing him to go on it I read everything I could find on the web - almost all was good from the people taking it. It is the warning labels that scare you !
If you go on 6MP there is a lab that can tell you if you have too little or too much in your system. The bloodwork is not cheap, but I think a test or two over 18 months is helpful. Check out Promethius Labratory for testing supplies and information.
