Keep going! The temp thing happened to me off and on. Sometimes it felt like the onset of the flu, but soon passed. Make sure you are getting at least 1,200 calories a day with the syrup because sometimes starvation mode kicks in at lower calorie levels and makes you feel that way. There were a couple of days I didn't hit that for whatever reason (mostly bad calculation) and the cold feeling would hit. Lots o' water as well for good hydration. You are doing great....keep it up!
