@petry Glad you found my question.
I take it you are sleeping on your left side on a wedge pillow. I do, however no matter how hard I try I very often, if not all the time, find myself in a lower position on the pillow and sometimes on my back. Of course the worst thing is on my back and low in the bed.
I have been wracking my brain to figure out how to help position myself not to turn over or slide down. All I can think of is to tie myself to something and that's not doable for various, obvious reasons.
Yes a nightmare in terms of the clearing and not getting a straight 7 or 8 hours sleep....uninterrupted sleep. Age apparently, for many of us, is a factor with sleep problems due to the changes longevity does to the body. Some one said in another post that the full moon can come into play regarding a good night's sleep. I think that is a possibility and can add to all the other factors. I did read, after seeing that post, on line about the moon being a factor and possibly affecting sleep.

So sorry about "cough to the point of vomit". That I haven't experienced....as yet.

Between morning exercise, nebulizing, air way clearance/huff coughing, prepping for breakfast, eating and eating slow....the morning is practically shot and then I have to get ready for lunch with all one does for putting a meal together. I have my main meal at lunch. Now if I spread the meals out so not to eat one large meal and have many small meals I might just call it a day that could be no more than health requirement routines, food prep and food intake and clean up.

I have given thought to taking medications for LPR/silent reflux, for at night/sleeping. That is when I truly can say "I think this is an LPR/Acid problem." However, I will continue to avoid the med's for now due to what I have read.
I am going to try to pay attention to what I have eaten during the day in relationship to it being a possible problem contributing to the burning tongue at night. I did suck on some cloves when I woke up last night and before I tried going back to sleep. Low and behold the burning sensation greatly subsided. Sure have to be careful with the cloves....don't want to swallow them. I will be making clove tea.

Thanks for your reply....I'm here if you have anything now or later to add to our discussion.
