Mestinon

Mestinon (Pyridostigmine) is an aceytlcholinesterase inhibitor used to treat myasthenia gravis. It inhibits the acetylcholinesterase enzyme from breaking down acetylcholine, resulting in higher circulating levels of the neurotransmitter.

Anecdotally, some ME/CFS patients have derived huge benefits from Mestinon, others none at all.
