I have been doing this w.o.l. since Oct.03 and had one chear on xmass night when I ate 6 choclate sweets,one hour later I pucked my guts up !! I think that my body could no longer handle the rush of suger.I learned my lesson big time that night,and to this day I have not cheated once.There are times when I have too many carbs-mostly alcohol related but never ever what I now know to be junk foods.I had a phone call from a friend of mine also on Adkins last night in which she said she ate some homemade chips on Sat. night and the old feelings of being tired and sluggish came back withen 24 hours.It was quite a shock to her and a lesson well learnt.So to sum up I think cheating may be a risk to far for your body to have to deal with.
