About 3 weeks ago I switched my diet to a whole food, plant based diet. I ate generally healthy before this but the switch includes A LOT of greens (mainly spinach), veggies, beans, etc. I was feeling decent on it but recently am not feeling well. I'm likening my symptoms to excitotoxicity - insomnia, agitation, anxiety like feelings (without being anxious). 2 weeks ago we had a new central air system installed. I then started feeling really icky (just about immediately after having it installed) and have ruled out any sort of gas as a problem (thank you, fire department and gas company), mold (inspection - waiting on air sample results but also just passed the VCS test again with flying colors) and we are having the ac removed tomorrow on the off chance there's something they installed that is bothering me. Today I had a couple of thoughts and would love other's input. Is it possible that by eating large levels of greens (and hence folic acid) that I could be starting up some methylation without taking the supplements to do so? And is what I'm feeling a result of this excitotoxicity? Or...could I be eating too many glutamate containing foods like mushrooms and tomatoes and is that what my problem is? Any thoughts on this? Thanks ETA: I am also taking B12 shots (methyl) 3.5mg(?) a few times a week.
