Hi again yxi
It seems that methocarbamol (Robaxin) is chemically related to meprobamate and carisoprodol. It's interesting to compare their chemical structures.
Do you find that Robaxin makes you drowsy? How much do you take, 1500mg per dose? I guess you need to take it every few hours, it's got a very short half life.
Methocarbamol is also known as guaifenesin carbamate. It's a derivative of guaifenesin. Guaifenesin itself is used in OTC cough medicines in humans and as a muscle relaxant in horses. As far as I know, guaifenesin has been used as an adjunct to anesthesia in horses, to relax muscles. Perhaps Racer will tell us more,
Despite the widespread use of guaifenesin in medicines for chesty coughs, there's little or no evidence that it actually works. As high doses, it does seem to work as a muscle relaxant in horses though!
Guaifenesin has been claimed to be useful in the treatment of fibromyalgia. Whether it actually works is controversial. To be honest, it would make more sense to use methocarbamol because it's got a longer duration of action.

Ed
