Hi, I’m glad that you’re ok and that your gp is helping. What did she recommend regarding sleep apnea? Let us know how you get on. When my nocturnal difficulties started I also suspected a reaction to utrogestan and I stopped taking it for at least a week but it made no difference so I’m back on 100mg. Hopefully you will find out what’s causing it soon. Despite being on the acid watcher diet my reflux has returned after being under control for months. I’ve found that my nocturnal breathing episodes can be triggered by more than one thing- acid reflux, my mouth drying out, not having the window open and now possibly allergies. I think it’s because all these things trigger mucus production in the throat. The hospital doctor said not to take sleeping tablets as it would be dangerous - my body is currently waking me up when my throat is narrowing but may not if I took sleeping tabs, and I guess some anti depressants might have the same effect too as they can make people sleep more deeply. Anyway the point of all this is to share my experience and hopefully you might benefit from it as it’s been months of trying to figure it out, lots of trial and error. At the moment I’m sleeping at 45 degrees so any mucus can drain away instead of collecting in my throat, but I’ve found if I sleep flat after about 3-4 am I don’t have any breathing difficulties, which points to reflux as the cause or the early rise in cortisol that has an anti inflammatory effect (a gp told me that) I really hope this info helps and you find out the cause x
Ps - apparently progesterone can relax the muscle that stops stomach acid coming up, so utrogestan could be a factor in that regard. I’m not sure if the oesophageal sphincter is capable of tightening once it’s been loosened..
