I understand, and meant no disrespect. Was pointing it out because its not an option people tend to think of, and in some places it's legal and proving beneficial.

Like you, I don't get sufficient relief from anti-seizure medication (Gabapentin, Lyrica), but if combined with a little Tramadol they see to work together nicely. With that combination my pain is halved, and from what I've read that's about fair enough to expect. Apparently 100% or close to is, in most cases, impossible.

Lyrica takes some weeks to get used to. At first I suffered headaches constantly, but Doctors advice to hang in there paid off as the headaches slowly subsided after about 2 weeks.

Hope you find your solution soon. Different things work for different people. Half the battle here is finding out what works best for you.
