Two nights ago, my rat did not ingest any Diamant. The Stage 3 Deep Sleep that night as measured with the Oura ring for the rat was 43 minutes. Last night, before going to bed, the rat took 5 drops of Diamant, and also a total of 1 tsp inosine powder ( 1/2 tsp at lunch and before bed to reduce his norepinephrine) and the rest of the supplements for the rat were the same. The rat's Deep Sleep was 1hr 50min. this is the most deep sleep ever in a night for the rat since starting Deep Sleep tracking. (the rat has been supplementing on and off for the last two months with 5 drps Lisuride 2x/day so dopamine and norepinephrine were high (as measured with the OAT Urine test.) The inosine may have reduced the norepionephrine last night and along with the diamont resulted in a lot of Deep Sleep.Stage 3 Deep Sleep seems to be much better as measured with an Oura Ring. My rat has about an 1 hour of Stage 3 Deep Sleep after 5 drops sublingual of Diamant before sleep. without Diamant, about 30 minutes. Everything else at bedtime was the same 4 dr. ProgestE, 100mg Theanine, 50mg B5 P5P, some milk + sugar.
