Seriously? Whatever!

Ok, so for the last two weeks I had days where I drank and ate bad things and I lost 2lbs. each week. This week I am an angel and don't eat or drink anything bad and now I have gained 8oz. ????? WTH I get that the body changes during the month and there are things that will throw me off but this is just nuts. Next week is my birthday and of course Valentine's day so I will have at least 3 days of eating what I shouldn't. So I should expect a 5lb. loss next week. o.O   It's all just so weird. Until Next week....
