I have taken gabapentin for over a decade. It helps my mind and body settle down. You could also try L-Tryptophan, 500 to 1000 mgs an hour before bed. L-Theanine may also help. GABA is the relax amino acid / neurotransmitter. L-Theanine can help with low GABA. GABA supplements do not get effectively used so L-Theanine is better.
