Have you tried gaba? I mean don't drive after till you find out if it makes you tired.. . Also I felt emotional for the first week took only 200 mg, because releasing ptsd is what it felt like. Gaba is what the dr gives to release muscle /nerve spasms. I now take a lot of gaba because my nerves need to un -seize if I get stuck buying groceries etc , just something else to try, if dr gives the go ahead. Not sure how it will react with gaba pentin ( biosimilar) though....
Also obviously magnesium and other hydration minerals potassium etc... I don't know what your levels or diet are,
Proper hydration and a good multivitamin might be helpful? (Methylated bs), always ask dr, I don't know your situation
