Any luck with gaba pentin for MCTD and all the attendant auto immune d

I was on gaba pentin after my teeth and upper palate started to hurt (after TMS magnetic therapy) . The gaba seemed to help . But I figured i could get off it after a few months once the TMS effects wore off .
Now my MCTD seems to be firing discomfort from heart burn, side pain, and my teeth are randomly hurting .
These pains are not crippling; however they fire into my consciousness constantly, sending me deep into despair . The fatigue and flu-like symptoms are very debilitating . It’s hard to keep going . I’m currently not on any prescription meds .
