I’m still running this experiment nightly. I’ve been sticking with 50mcg, as I see no real difference in how well I sleep or how quickly I get drowsy between when I use 50mcg and 75 mcg. As I mentioned in this thread (to-go and self effects), one night I swiped the tubing under my nose three times instead of spraying, and I got the same effect.
I’m not getting a next day crash, I’m seeing no acclimation, no reduction in effect.
As soon as I get my TAK, I’m going to start testing that in the same manner. I may take a week or two off in between, to get back into my normal sleeping pattern.
