Food issues

OK I have food issues.  One week I am failing the workout because I am not eating enough.  So I stopped counting calories in an effort to not under eat.  So now I am either overeating or under eating but eating all the wrong crap.  I need to sit down, plan out some meals and snacks and figure this shit out.  Because this isn't working.  I couldn't even finish the workout.  I only 20 mins of the work out before I started getting dizzy and couldn't go on.  GRRRR so frustrating.  Ok well tomorrow is a new day and we can try again.
