Feeling off Track

So as you know I went out last night.  As far as not blowing Points goes, it was a success.  I only went 1 Point over.  Today I have stayed within my Points, but have not worked out.  I really want to, but all day I have felt dizzy and light headed, so I figured I should probably take today off, try and get some rest tonight, and be right back to it tomorrow.  I hate when I don't work out.  It makes me feel like I'm 5 times larger than I am.  I keep getting so disgusted with myself.  Especially when I don't have a great week  (like this past week).  Tomorrow's another day.
