After my RSD spread last year and I got much worse...I went a whole year with anywhere from zero to at most 3 hours of sleep a night and none of it was more than 30 minutes at a time. I was such a mess.

When the doctor put me on amitriptyline I started to get 3 hours of sleep a night regularly and that was usually consecutive...seems like a real blessing. In Feb of this year I started treating with tDCS and after about two months I started getting more and more regular sleep. It has only gotten better. I am off the amitriptyline and generally get 6-8 hours of consecutive sleep a night now (unless I need to get up early for work). I cannot tell you how wonderful it is to be on a fairly regular sleep schedule after a year of basically no sleep.
