I've been taking Doctor's Best Benfotiamine 150 for a few months and I truly believe it has helped with my SFN symptoms. The dosage according to what I read on a post I believe from MrsD is 300mg for the 1st month and 150mg after.

I also take Gabapentin (3) 100mg capsules WITH dinner. I can make it through the day but night can be bad. It took 2 weeks for my body to get use to it. I'm sure it helps with the burning and twitches because about an hour after I take it my sensations are considerably milder. If not for that I would get off of it.

I also use Aspercreme with Lidocaine for burning/pain and Morton's Epsom Salts for twitches. Also Topricin Cream is good.

I am looking into getting a compounded topical cream that includes Gabapentin and some other ingredients. Your doctor would need to be involved with that. There are posts on this if you search "compounding cream"

I didn't respond initially because I am retired and didn't fit into "Full or part time?" I was a teacher and if this had started when I was working I can't imagine what I'd have done. Probably been fired! Sleep is the minimum requirement to being surrounded by middle school students all day long
