Amitriptyline
"I give it an 8 or 10.....the other end would be a 1/10 :)
DO NOT take this during your waking hours...Yeesh
This was prescribed for pain related to Neuropathy. I was told to take one before sleep and I would be good to go. Suffice to say, I have no idea if I hurt in my sleep because THIS PILL is the proverbial sledge hammer.
 I have an odd metabolism. I take one AROUND 4pm and I start yawning by 9....and do not wake for a MINIMUM of 12 hours.
SO!
If you need sleep...this will do it. If you need pain relief at night...well, I suppose if you are unconscious, that works as well :) Sometimes I wake with back pain from having to pee so bad. if your bladder is weak, you may have "other" issues"
