Apologies if this veered too much off topic. I've been kicking this around for a week or two, and felt the need to add recent events and post.
It's 5am, I haven't eaten in 12 hours, had anything substantial to drink in about 8, have been sitting on the toilet for over an hour, and instead of doing something about any of those things I'm editing a comment to fix a typo.
That's what sleep is for, staggering your doses, or just taking something that also tends to have sleepy affects at night like Nortryptiline.
