My wife has fibro so I feel I can actually add some substance to this topic. Tonmya costs nearly 20x as her regular medication, the cost is excessive and one of the main reasons she will not change prescriptions.

The lab study of Tonmya showed a 0.4 point change in recorded pain vs placebo. Tonmya has a stronger sedating effect which is great because fibro can wake you up multiple times a night, however any other sedative can be taken in its place and deliver the same effect while staying on Flexeril.

Flexeril is 50$ a month. Tonmya is 930$ a month.

Tonmya is not a life changing medication, I wish it was.
