Vedana: does it include feeling sleepy, dizzy, alert…

I am a (somewhat lackadaisical) follower of S.N. Goenka's meditation teachings. After a couple of 10-day retreats and reading some articles such as this: http://www.vridhamma.org/Why-Vedana-and-What-is-Vedana I'm still not sure how to regard sensations that at least in Western terms are not simple sensory input, but which also do not imply any attachment or revulsion — feelings like the ones above, or hunger, fatigue and so on. Are those vedana, and hence proper objects of mindfulness?
