That's a shame, Stacy. I have never heard of LDN raising one's BP, but I don't blame you for being extra careful.

I know that here are some side effecs at the higher doses of Naltrexone, such as liver problems but not at the low doses we take for MS. Insomnia only happened to me, temporarily, when I went up to 4.5mg, too fast.

Talk to your Doc/Neuro about it and see what he/she says. I hope you can still give it a try.
