Yes your right it isnt a sleeping pill but it has similar effects to one. Im not taking medication because i can still just about function and go to work etc although it is painful i need to be able to think clearly for my job. A lot of these meds for pain interfere with the thinking and concentration power. Im trying alternative methods before i start on pain killers because id like to avoid a long term addiction if at all possible. Im trying TCM at the moment. My gp is checking for b12 and diabetes to try and find some underlying cause.
