Heyy GLC! Sorry to hear that you're feeling your symptoms again...and excellent encouraging words about not giving up!
I've tried eating raw garlic for relief a while back, but the raw whole cloves are really gross to me and made me feel sick, not a "POIS sick" though. Doesn't bother me if it's cooked or if in a capsule.
Almost had an MRI around the time I started feeling symptoms, but decided not to because of the fear of not being understood or taken seriously enough regarding symptoms...Plus I had my doubts about them actually seeing anything abnormal.
I still think an MRI is a good thing for a POISer and I hope something can possibly be gleened from it. Let us know the results if you get one! Thanks, and hope your symptoms clear very soon.
