@daisy17 In my experience, because I also have ME/CFS, most of my meds are low dose. Sometimes they work differently if they are low dose rather than normal dose. For example, LDN (low-dose naltrexone) is 4.5 mg, but Naltrexone normal dose is 50 mg. This LDN helps with my pain.
It appears that, if I were able to take Tonmya, as a geriatric patient my dose would be 2.8mg. I see that the daily dose for Flexeril is 30 mg. So it appears this is a very low dose. However, I am not a candidate, from what I read, as I do have CHF, heart block, and heart rhthym disturbances. So, as excited as I was to see this med for fibro, I don't think I can get it. At least it would be covered by my insurance, whereas the LDN is not--it has to be compounded. Darn! I will ask my cardiologist though because I will see him at Mayo Clinic Phoenix in December. Perhaps this low dose would not be a problem, whereas the regular dose of cyclobenzaprine would.
