insomnia
"My bedtime got later and later until it was early morning as I wasn't tired and never fell asleep when I went to bed. Brain was overactive continually. Bought packet of Dosylamine and took one tab an hour before bedtime. Relaxation kicked in one & half hours later and slept solidly for 12 hours! Totally useless the next day as groggy and no energy. Next night cut the tab into quarters but that proved too little as had no effect. Will take half tab tonight which hopefully will be the right amount. It relaxed tension and brain activity and teeth gritting, so for me seems a muscle relaxant enabling my mind to let go and shut down.  Subconscious anxiety is my problem that prevents sleep. I am a worry wort."
