Hope you are sleeping better since this thread, bud.
Whenever i hear people having trouble falling asleep i am compelled to recommend what i do, it almost never fails.
Maybe you do this already, maybe you dont (maybe you cant, hopefully not the case) but if you can, plank. Brush your teeth first. Then as long as you possibly can (and i mean Possibly, dont stop until you literally Can Not stay up), plank as straight as you can either on your toes or knees, hands or forearms (whichever is hardest but still possible), until you very nearly collapse. Then right to bed. For me at least, the unclenching core is such a relaxing, body-encompassing feeling that it tells everything else its ok to shut down. Then my mind says fuck this shit im out.
