Hi Nick!
I am new to this site, as of like 5 min ago haha, but happened to come across your thread as I was browsing around. I think we have gone through a lot of the same stuff and we are about the same age. I know it's not the same for each person, but I was awful on hydrocodone! When I tried it, I felt like it heightened my symptoms and I also felt like I was in a super brain fog for about a few days. I know that I am more sensitive to medications post brain injury, so maybe you are too? And I also agree that you are over-working yourself, so I hope you can find some peace through the craziness =)
