ive had fatique at times too. i lift 3x a week, exercise doing other stuff 2x a week, eat plenty of good foods and get 8 hours sleep nightly. when i feel fatiqued i just try not to worry about it and not let it stop me from what im doing. as far as im concerned im just getting fatiqued becuase my body is using so much energy to deal with problems in stomach and its just becoming unevenly distributed.
