I dont think with dank's condition he can do alot of exercising.
But I do get the point about staying busy for a full day will help you sleep better at night. Just as not doing anything all day could make you not sleep. I have done several things. One, I no longer have a tv or a computer in my bedroom. Its for sleep or hanging my clothes in the closet only. Also I get up at the same time, usually 9 am, and try to make as full a day I can with my disability. I try to go to sleep at the same time at night if I can. If I cannot after 30mins, I get up. I used to take an ambien. Those no longer work for me. I now take temazepam. Those work sometimes. If I dont think the temazepam is going to work, I take my promethazine for nasea , and usually make a vodka stinger. I prefer not to drink if I dont need to, and I never drink with any other meds. But drinking a couple cocktails usually does the trick.
Then awake, rinse and repeat.. lol
