"i slept well as a young adult, but by my mid forties i was only sleeping about 4 hours per night, and only 2 or 3 hours if i was under stress. it finally got to where i having a lot of anxiety, grinding my teeth at night (with a sore jaw in the morning), and even started showing symptons of ocd. i started elavil (brand name in canada) 10mg at bedtime six years ago, and it has made my life so much better. i sleep a solid 6.5 hours every night, and feel great. the teeth grinding and the ocd symptoms both stopped within the first 2-3 weeks. it took a few days to start taking effect. i also had a slight tremor during that first few days only. i had a somewhat dry mouth for the first two years or so, but not at all now. 10mg still works for me.."
