Have Fibromyalgia which can cause chronic fatigue. I take 50mg of Amitriptyline every night, this is to help with my sleep which in turn is supposed to help the chronic tiredness and the pain.
However I'm not sleeping at all well, waking several times a night. I feel so drained, don't know whether sleeping pills would help, or whether to increase my amitrptyline to a slightly higher dose.
