back story: at every point in the titration process, it's always taken close to an hour before I feel any effects of the first dose and can get to sleep, so it's guaranteed that the first dose will only give me three hours sleep if I want to piggyback the second dose on its effects. (I'm making sure to check the times I'm eating. I've tried going to sleep in a completely dark room, doesn't change how long it takes to work).
So about the problem with the higher dose:
I may have just titrated up too quickly, but I moved to 4.5X2 (no OD signs or anything like that), I've just been waking up way before my four-hour alarm WHILE I can still feel Xyrem very much in my system. Last night, for instance, I took my first dose at 9:30, went to sleep around 10:30, woke up at 12, alarm was set for 1:30. Knowing I could have taken my second dose then, I should have, but I didn't, because I thought, "well, I still feel this Xyrem VERY STRONGLY right now, so I'll just sleep until my alarm." My thoughts were if I only got 1.5 hours of sleep on the first dose, and I took the second dose at 12, I'd be up for the day at like, 3 a.m.
I woke up at 1 (AGAIN before my alarm), Xyrem completely out of system, so I had to wait another full hour before it kicked back in and I could fall asleep. After the second dose, I got maybe three hours. Almost six hours total, but with the hour of being wide awake in the middle of the night.
At 3.75, I would always wake up to my alarm going off, so I don't get why I wouldn't sleep harder at a higher dose. (Note: I HAVE NOT been abusing it, so I can't have a tolerance!)
My Xyrem nurse said it could be that I've been drinking too much caffeine (ETA: too close to bedtime), which is true. I've also heard some people say having a WAY too empty stomach affects their Xyrem. AND I've been ridiculously stressed. Has anyone else has anything remotely like this happen to them?
