I have just found this post- I am a bit late- but I have a salicylate/ amine etc intolerance and I go into shock. I get poisoned by salicylates like you do if you take an overdose of aspirin (pure salicylate).
I had other problems that led to this intolerance and I now understand that people with this intolerance need to fix their bowel and liver because this is where you process this natural toxic chemical. When my infection and candida is worse so is my intolerance. I know it can be overcome.
When reading your post I am amazed that you can do the Master-Cleanse because of the lemon!!!!! How do you do it?
