So I went to bed just before 11:00 last night, and fell asleep well enough after I got over my initial hyper-ventilating. I think I need to let my body relax a bit, settle for a minute or two before I put on the machine, maybe while it is warming up the water. Then I slept until after 1:00. That might not seem like much, but it was well over the 90 minute sleep cycle I normally have i.e. it pushed through it.
The problem was I felt like (a) I needed to go to the bathroom eventually / not urgently and (b) I had a tickle in the back of my throat I wasn’t able to clear. Took a break, got up, went to the washroom, And the tickle became reflux. Not sure if that was a reaction to swallowing too much air, or something else. Going to try clearing my throat more before I start tonight.
Went back to bed eventually, decided to try it again anyway, vomiting or not, and had no issues — slept again for more than 2 hours. So it’s working, and I slept more than the previous night with the machine (about 4 hours the first night, probably about 5 hours the second).
And I woke up this morning with my head the clearest it has been in months. I felt great. Until I got up and started doing stuff, and then some of the fuzzies came back in. And this evening I was really tired and partially two-headed again, but it held off longer than usual today, another encouraging sign. Plus my right jaw cracked this morning, releasing a lot of tension, which I think is because I haven’t been clenching and grinding as much either. Another bonus.
Still cautiously optimistic.
