I tried enzymes and had such an extreme reation I just knew I was on to something. 12 hours after I took the enzymes -- I got the worst cramps in my lower abdomen along with a fever and sweats that literally soaked the bedsheets. Eventhough it was scary, my gut told me (parden the pun) that it was a positive response. Almost like the enzymes dislodged something that my immune system could see and attack. I know that sounds weird but that's how it felt.
I've been afraid to try the same brand again -- so I'm looking for a milder version of what I took. I'm very curious to find out what brand or enzyme combination you're friend is having success with. And also if she had a similar initial reaction.
