Kat - I've been doing LSD/NSD for about 6 months now. I know it definitely works in that it lowers my pain levels by 1-2 points. Not a panacea, but worth continuing over the long-term. I had initial high hopes that NSD would be the end-all treatment, but have accepted that for me I still need to complement it with mainline medication.
Thanks for sharing your thoughts and experiences.
