If I couldn't get a prescription for enough Mestinon, I would try huperzine-a. It can be bought without a prescription, and it works like Mestinon. That is what I personally would do. It may or may not be safe, so please do your own research.

Because huperzine and Mestinon both work by allowing acetylcholine to build up in your system, it's important to know that if you take them both together, you're risking overdosing. Too much acetylcholine is very dangerous. For that reason, if I were taking huperzine, I would only take it when I had no Mestinon in my system. I have seen huperzine recommended as a supplement for MG without this warning, which is very irresponsible.
