"i have been taking 25 mg of doxepin for 17 years, i always could fall asleep, but if i woke up during the night, i couldn&#039;t go back to sleep for hours. doxepin was like a miracle to me, i was never groggy the next morning and it didn&#039;t make me sleepy and groggy right after taking it.  it just lets me go right back to sleep if i get up to use the bathroom.  it still works after all these years, not as well though.  i have weaned myself off of it, but i start having hot flashes off and on all day...so i start taking it again.  and after being off of it for a few days the sleep problems seem to be back...so i may be on this for the rest of my life. i have recommended this to several friends and it has also helped them."
