"my husband has bi-polar disorder and suffers from chronic back / sciatic work-related pain. he&#039;d only been (restlessly) sleeping 2-3 hours a night for past 10 years. this had increased his mood swings and cyclothymia to unmanageable proportions!!
uk doctor prescribed 10mg amitriptyline, to be taken at night 2 hours before bed. after two weeks this was increased to 20mg per night.
the effect has been nothing short of miraculous.
he sleeps really well for 7-8 hours a night, wakes refreshed &amp; cheerful.
it&#039;s helped him cope differently with depression - staying calm &amp; getting cbt therapy. (something he&#039;d never have volunteered for in his &#039;normal&#039; bi-polar anger / depression cycling).
has also noticed lessening of pain. 
it&#039;s saved our marriage."
