Hi Trish,
I'm very sorry to what happened to your partner. It is very similar to the MG onset I experienced when I was 68.
Could you tell us what are his daily dosage for pred and Mestinon?
Cait is right, false routes when swallowing could be dangerous so you have to adapt your (at leat his) meals to what he can easily chew and swallow. Take more meals in smaller quantities in order not to fatigue the muscles involved in the swallowing process. For the same reason, avoid talking when eating.Avoid products like salad which require much chewing for little profit. I found raviolis easier than spaghetti. Use the mixer/blender for meat or vegetables and use spices to improve the taste of such food. Liquid should be sipped by small quantities and jaws should be 2 to 3 inches close to the chin, that opens the throat to the maximum.
Calcium and vitamins D3 should be taken when pred is prescribed, eat one banana per day to get more potassium.
Sleeping problems, glaucoma are possible side effects with Pred.
Do not hesitate to ask questions, many people will be happy to share their own experience.
Take care,
Maurice.
