insomnia
"I have sleep apnea but can't stand a mask on me, and without drugs I wake up constantly by stopping 
to breath. I take 75 mg of diph. an hour before I want to go to sleep, have a couple puffs of indica (night time pot,) ( it's legal here) and it works like a charm, I stay asleep for 5 or 6 hrs which is a long time for me, little groggy when I wake up but it goes away after a couple puffs of sativa (day time pot)
 I've been a toker for 49 yrs, it's good for a lot of uses. I am 66  My doctor says he agrees that pot is easier on the body and mind than prescription drugs for anxiety, insomnia, depression, pain,and loss of appetite. They make edibles, gum, etc for those that hate smoke."
