My sleep got worse on reta too. I am just two weeks or so into it, so I wonder if anyone further along knows whether it fades. Either way my regular sleep supplements do plenty: magnesium threonate and citrate, theanine, plus liposomal apigenin (the chamomile compound, works so well its crazy). But even on that stack, which normally knocks me out within 30 minutes, reta wrecked my time to fall asleep, 1-2 hours. Once I am out, sleep is fine, but with an alarm I risk fewer hours. What helped a lot was strength training. Im not a late gym person, but on reta about an hour after each session I get so sleepy I could nap (I never nap). Weights 2 hours before bed brought my sleep onset down to under 30 minutes. The catch: I would have to lift every single night.
