Immortal to fall a sleep you need serotonin.
U can buy the precursor of serotonin and thats tryptophan an aminoacid.
Take that with 3 gram honey or grapesugar not with normal sugar…it will help for the trytophan to enter your brain.
If you are from the U.S.A then u cant bye trytophan…illegal…so in that case buy bananas…eat 2 or so with glass of milk and some honey.
Bananas, turkey meat, milk and cheese contain also tryptophan.
your body transforms it into serotonin and u fall a sleep more easy also while wilding lol. For that process is also needed magnesium and vit b6, if u want to optimize it lol.
