Question about schissandra - is this the best cortisol lowering supplement and does this need to be cycled? Any other recommendations for supplements to lower cortisol at night?

I ask because the King of Unusual Symptoms (aka me) has trouble sleeping well after heavy lifting days (even if I train early in the morning). I always have trouble falling asleep, often wake up hot and sweaty, and end up usually having a really light and shit night’s sleep.

I have tried ZMA but unfortunately my gut can’t really tolerate magnesium - causes gas and bloating - which again fucks my sleep...
