I did 6 months no carb (since October) then kinda indulged, then another month no carb, then a few weeks ago indulged in all the carbs, sugar and fast food I could eat. I felt fat although everyone said I looked the same. It's an internal disgust I feel, so I am back on 0 carb (except from fruit/veg) until August.
It's an internal battle you have to fight, when I completely abstain there are no cravings, when I have a "cheat meal" or whatever the cravings can creep in. I prefer to give myself a few months without then indulging, realise why I didn't want this crap in the first place, then cut it out again.
