"i retired over 3 yrs. ago and almost immediately my schedule began to change, ending up in a situation in which i couldn&#039;t fall asleep sometimes until as late 5 or 6 am, and not get up until around noon!  yesterday my lung doc, who also does sleep studies, suggested doxepin.  i had already had a bad experience with it many years ago - 10 mg. it put me to sleep alright, but i felt like a frigging zombie the next day .he told me that was too strong a dose and recommended half of that.  he also told me that most insurance companies won&#039;t pay for it in any dose except the generic 10 mg. capsule.  not the 3mg. tablet or the liquid. so, i half the caps nightly in water. slept fine;no hangover. retired 11:30 &amp; up @ 8.hope tonight&#039;s same. dose is key!"
