Hi Kat,
Have not tried Gabapentin. Nurtec and the other flavors/delivery did nothing for me, no headache meds were of any help. I have yearly bloodwork and not deficient, but I have started vit B and D per doc's recommendation.

Haven't tried yoga. I lift at the gym 3 days a week for almost 5 years now. I forced myself to be consistent even through the worst of times. Not sure why.

Mindfulness did help. When I was told that was basically only solution, I wasn't accepting, but ready to TRY ANYTHING to escape the misery. I learned through counseling some things that seem like common sense afterwards. Life is better when not focusing on negativity. I learned I was very judgmental of others especially myself. I accepted I can't control other peoples emotions. The reduced stress from these and others made a noticeable difference in psychical symptoms. I continue to work on other stresses like staying married.
