Has anyone had some success with Mestinon and then tried other meds/supplements AND found something that works the same or better?

I was hoping to find something that works the same or better for me... but maybe has less side effects or longer action. Or any other benefit. Not necessarily to replace the Mestinon either but something I could use part of the time. Kind of worried using it too much.

Mestinon does work fairly well for me and I'm seeking advice from people who think it's helpful.

Thanks.
