I'm actually down to 0.2 myself and I actually started to experience the characteristic sleep disturbance effects of LDN.
Probably because it was metabolized more quickly and I started to experience the endorphin recovery sooner.
That being said, I still woke up rather easily and feeling reasonably well rested as opposed to the absolute death I've been feeling like the last few days since my side effects changed.
I started experiencing seriously bad anhedonia, I felt like a piece of plywood, I couldn't enjoy anything, there was very little dimension to my personality.
Since titrating down I've noticed an immediate difference, I think that for some reason I'm very sensitive to medications, but even at dosages as high as 0.50 I seem to still be experiencing the opioid blocking effects long after I should be.
The 0.20 dose seems to suit me a lot better at present.
I woke up and had to immediately get some water to drink, but at least I felt energetic enough to get up and do that, my mood wasn't bad either, I woke up today feeling rather good from a psychological standpoint which makes dealing with side effects all the more easy.
There is such a thing as dosing all the way down to 0.1mg, so don't be afraid to go down that far just to try it out.
