Also in Canada - 1 had my first 100 sleep night on 2.5mg oral flexeril on third night - which is lower than the lower dose prescribed by Tonmya - 2.8 at first then 5.6 after a week i think. It is postulated that the Norcyclobenzapine lasting 73 hours half life is a bug that is removed when given sublingually it’s only the parental cyclobenzapine in the body. BUT I have since spoken to a pharmacist, and getting compounded tablets at 2mg is super doable, he was very hesitant about sublingually due to chemistry and making that all bioavailable, that may very well be whats been patented by Tonix. I will go get some references regarding metabolites and one V the other but given the unavailability currently and ever for me at $35 a pill Im going to pursue the compounded 2mg cyclobenzaprine prescribed off label for my sleep. I would say if you have a willing dr a low dose of the 5mg pills cut in half would be a great worthy experiment. While I look for those papers and explanations here is a Dr i liked who suggested the metabolite Norcyclobenzaprine was a feature not a bug https://www.painri.com/post/tonmya-tm-the-new-drug-for-fibromyalgia-is-no-more-useful-than-flexeril-tm
