You should know, though that ideally - when we're 'clean enough' we don't react to things so sensitively. When we do - it's indicative that our body balance is already full. It can't take anymore.
I think it's partly a terrain/candida thing. If you're already full and you ingest something that's going to trigger more candida, you'll feel it immediately. I'd wager it stands to reason then, that when we're less toxic we can enjoy a plate of nachos and be just fine. Until then - if I have a choice - I'll choose eating an excellent diet over SSRI's any day.
