Problems with my IPAs

Also on my latest ipa I cut my water in half with distilled water that was charcoal filtered and added 5g Gypsum only to mash. Haven't bottled yet but it sure smells great and no off flavors in the hydro tube I sampled

I'd suggest too many sulphates are upsetting your system, then you're using a load of water from your body to try and dilute them which is giving you a bad head ache.

As to why you're not getting sick after they've conditioned more I don't know. The only thing that could be is more yeast in suspension. Magnesium is only really needed for yeast health so adding that is pretty pointless as they don't need much at all.
