Rhodiola Rosea is a miracle for shift work. I began using it for sleeping issues/ libido about 1 year ago. Wow has it helped. It works by regulating the body's brain chemicals and hormones. I actually have a health business now that sells the stuff, so I buy my own brand. I find it to be the best quality one I've had out of the 5 kinds I have used.
