@Craigy  Baclofen 

I have not tried that one yet, which could soon be in my system if the one I am taking now continues to show little improvements.

There is only 1 tablet that I am taking to control my nerves and that is “Baclofen”. I believe that the dosage I am taking is quite low as I was prescribed 2.5 mg to be taken once a day.
