Can complete blood count results change in over a couple months? mine was checked three months ago but i'm still have exteme fatigue. check again?

Yes: However, I doubt this will reveal a new anemia, because you list that you carry a diagnosis of alcoholic hepatitis. Now, I doubt that diagnosis, but it tells me you need a competent work up of your liver troubles, including ruling out Wilson's and lipoid hepatitis, and other causes, even carbon monoxide in the home. You need a capable and caring physician and a full work up.
