Rollercoaster

I'm struggling a bit at the moment.

I go through a definite pattern of phases when I try and lose weight. Good, bad, good, bad etc etc ad infinitum.

Lately though it feels like the bad phases seem to be lasting longer than usual.
Over christmas I STS for 2 weeks, which I was very happy with, but I would class that as bad period. Then I lost 1lb, then 2.5lb which is definitley a good period. I was hoping it would last 3 or 4 weeks but then last week I STS again, and it loks like I'm on course for another STS this week.
Its very frustrating.
Last week I knew I had been good so I put it down to it being * week. But this week?? Who knows. I have been going for it exercise wise, which I have heard can affect weight loss, but I have been drinking at least 2L of water a day which I thought would counteract this.
I know I shouldnt weigh myself during the week but as I have said in earlier posts, I hate not having some idea of how I've done before I step on the scales. I would have had a MASSIVE shock last week if I hadnt of done that, as I thought I'd done really well.

Another thing I've heard recently, is that your weight loss/gain is actually dependant on how you've done the previous week, i.e. if you have been naughty and eaten say 10 chocolate bars, it takes a week for it to show on the scales, its not immediate. Buuuuut, if that were the case, then I would be showing a good loss this week as I was so good last week.

Oh I don't know, I reckon I definitely think too much about it, and in too much detail. But I just cant help it!

I guess we'll see later when I go to class, but I'm not looking forward to it (not that I ever do of course).
Expect an update tomorrow..... fingers crossed.
