parasite cleanse questions

hello, I have a few questions for Humaworm or whoever can answer. I plan to start parasite cleansing after I'm done nursing my baby which probably won't be for another 6 or so months. I know it's not safe to cleanse while nursing so just in research mode at the moment. My question is I've tried humaworm before and the side effects were so bad I had to stop. I had a feeling of not being able to breathe, tightness in the chest and heart palpitations. I understand that I'm going to have die off and perhaps not feel well but these symptoms were just too scary. So my question is what to do? Any suggestions on where to start with parasite cleansing? Oh I also had a similar reaction on barefoots dewormer. Right now I'm taking DE as far as I know this appears to be safe during breastfeeding.

Thanks for any feedback you can provide.
