i also find if i deviate from my bedtime routine ,sleep is hard to come by. even if i already took 2 showers that day,i have to shower just before bed. no sitting around in pjs is another no-no before bed. shower,read 1/2 hr and no matter how good book is ,i have to stop or i can't sleep well. i also keep ibuprofen at bedside due to aches and pains that come in the night!
