insomnia
"I have been taking doxylamine for the past 10 years. This is a Kirkland product, 25mg tablets. If I take a whole tablet it knocks me out and I am numb in the morning. Still, it is the only sleep remedy I've had success with and when I try to discontinue, because of the uncertainty of long term use, I don't sleep. At 76, I am doing my best to retain my cognitive function and I have serious questions about the long tern effects of this drug. To sleep or not to sleep, and I will choose sleep whatever the risk. I find that I can take 1/2 tablet and that has the desired effect...even 1/4 will sometimes do it. 

I would love to hear about the experience that others have had, For me this is the only thing that works, and I have tried everything."
