Sugar Withdrawl???

Today is Vlcd day 3. I weighed in at 247.6, that is up 1.6 from yesterday. I knew my weight would be up today because I threw caution to the wind yesterday and had sugar. yesterday afternoon when I came home all of a suden I became totally drained and had a headache. I had been fine all day. Could I have been suffering from sugar withdrawl???  Is there any such thing?  Has anyone else ever experienced this while dieting.

As I mentioned in one of my earlier posts, my eating issue is not in over- eating or pigging out. I am a sugar, carb-aholic. Although I believed that NY's Mayor Bloomburg was far out of his lane when he tried unsuccessfully to ban the Big Gulp. I am one of those fatty's that drink all their calories. If I am honest with myself, that is why I have began regaining my weight. I was consuming one, sometimes two daily. Once I buy it I sip on it for hours. I tease the secretary at my school when she looks at me like I am crazy at 7:30  in the morning arriving to work with a huge soda in my hand, I tell here that my smile is in that cup. I would not be able to smile and be nice to my class without that soda. Some people drink coffee and smoke cigarettes, my drug of choice is pepsi cola.  7-11 is the worse because they have a cherry button to press as you fill up the cup that results in the most devine tasting soda ( picture me salivating at the mouth as I say this like Wendy Williams when she id describing any food) Lol.

I do digress, as I was saying all of a sudden it was like my blood sugar bottomed out and I felt weak and exhausted. I was on a roll, I had not injested any sugar since Saturday. But alas, what did I do when I started feeling weak? I drank a pineapple soda and ate a pack of Linders Chocolate Chip cookies. Yeah I know there were many better choices ( feel free to comment and leave suggestions) but I sure felt better after. That isuntil I hit the scale this morning. I also did not get in all my water.

I am really interested to know if anyone besides me has ever felt this way after a few days of dieting?
