Hi, I don�t know if this is a common side effect of the chemo or radiation but after 4 weeks post treatment I generally feel ok, even good at times, yet it still seems that I�m have trouble getting good sleep. While my body feels tired, my muscles seem to be tense, like I had too much caffeine or something. I try to get some exercise during the day so I will sleep at night, yet come 11-12 o�clock and I�m still wide awake. So I still take two Tylenol PM�s to get to sleep. Even then I don�t seem to get a good full nights sleep. Even during the day I might feel tired like I would like to take a nap but when I lay down my muscles feel tense like on a caffeine high. I�m tired but just can�t get good sleep. Is this normal? Is it long term or will it go away?
