Starting maintenance phase of ASAP, avoiding sugar and starch

I am on my third day of maintenance now and my weight has been across the board. On my final day of ASAP, my weight was 153. On my first day of maintenance, it was 155 (I had tuna casserole for dinner and pumpkin pie... BIG NO NOs..) My energy level plummeted after I ate and I just wanted to curl up and go to bed at like 7pm! I woke up that day at 9am, so there was no reason for it other than my  body shutting down by having to process all that sugar.

Yesterday I woke up with the scale reading 156 after breakfast (I usually weigh first thing in the morning since it gives me the most optimistic results).

So yesterday I only had coffee for breakfast, 2 apples and beyond tangy tangerine for lunch, and a small square of casserole for dinner with the rest of my supplements. Today I weighed in at 153!... So I am a little confused what my results have been.I think its safe to say 153-155, which would  be 10-12 pounds off in 3 weeks!

I am thinking I haven't been drinking enough water on my final days of ASAP so my  body started to store it. Yesterday I drank plenty and this morning I was pleased with my weigh in.

I have been checking measurements too and everyday they have been the same except my waist after I  had that casserole on my first day was a .5" bigger until it all got digested.

We got the SlenderFX Chocolate shake in the mail a few days ago so I will start taking that instead of lunch. This is how I like to make it:

1 cup almond milk
2 scoops mix
1.5 cup ice
1 Tablespoon of peanut butter
 BLEND until smooth

I think I will opt out of the peanut butter if I am gaining too fast. And perhaps use water instead of almond milk. Either way I like to give it volume by blending it. And since I have those sweet drops maybe I'll add some english toffee to it. That flavor is my new fav.
