I appreciate the responses, and the encouragement. I realize there are many with more severe cases than mine, so I hope they can find some relief soon. Taking the mestinon every four hours has just become a way of life [even the 2am dose], and the results are worth the bother, so I too hope I don't get immune to the medicine after awhile. So far, along with relieving my throat problems, the mestinon has also given me some help with my hands [I thought the pain, stiffness, and weakness was from having Lyme's disease a few years ago] and I have had stomach problems for years but the mestinon has even helped regulate that somewhat. I've tried taking 60mg, but that is too much for me, so I keep it at 30mg and it works great.

Again, thanks to you all, and I pray God helps each of you.
