I've been following resistant starch posts here and elsewhere for a few months, and had been experimenting with potato starch and probiotics recommended in the resistant starch thread here. I had to take antibiotics in mid-March, which set me back to zero, but since the beginning of April I've increased my fiber, gone off and on potato starch, and consistently taken a probiotic every day. When I started I was waking every 1.5 hours, with occasional nights where I woke every 2 hours. I would "sleep" for about 9 hours. Getting to sleep is not an issue for me. Now I'm waking up 2ce, sometimes 3 times, and I sleep 7.5 to 8 hours. I slept through a massive thunderstorm a few night ago, which feels miraculous. I don't take anything for sleep, or anything that affects sleep (like antihistamines). I haven't changed anything else in my routine, except for adding LDN at 0.25 a few days ago. [When I tried LDN in February at 0.5, it didn't affect my sleep.] The probiotics I use are AOR Probiotic-3, Prescript-Assist, and Garden of Life Primal Defense Ultra.
