OK, putting all these pieces together, my working hypothesis is that the liquid is slightly different and you are still adjusting to it, and the time of day and your biorhythms is a factor, and it used to be 10 and 2, but now its 8 and 1 and you’re reacting as if those doses are too much for you.
So, my hit is to wait another couple of weeks to settle down on the liquid, and then pick either the 8 or 1 dose and taper one of those a bit. What do you think?
