Welcome to the club. It gives me a lot of pain to hear people coming on this forum time and again, referring to the lams and using phrases like "I used to be able to tolerate vitamin C," "I'm confused," "I don't know what to do," "I'm having trouble tolerating my Lam protocol." It makes me sick knowing innumerable people have fallen of the Lam wagon, unable to tolerate vitamin C anymore, sicker than they were before consulting the Lams, and several hundred dollars poorer for investing in them. There is no money back gaurenteee with the lams, and of course, they won't be able to return you to your prior health before you trusted them with your precious health.
Listen to your intuition. You're paying them to help improve your health, not damage it.
