GenCare - Mucus Relief DM (150 Count Value Bottle) Dextromethorphan HBr 20mg Guaifenesin 400mg | Generic Mucus Relief DM | Immediate Release Uncoated Cough & Mucus Expectorant Pill

I take one of these with my bedtime pills, and another if I start feeling crashy during the day: https://www.amazon.com/dp/B0B9ZXSN92 I just had an almost crash earlier today and this helped ward it off. I haven't had an actual crash since starting them. I also take LDN and Hydroxychloroquine, both of which seemed to help a little.

I've been taking one of these at bedtime, plus one more if I feel crashy: https://www.amazon.com/dp/B0B9ZXSN92
