The Scale Goes Down

Saw my GP today for my weekly vitamin B12 shot and weigh in.....I'm down 5 pounds bringing me to 235 pounds for a total of 26 pounds lost in 4 weeks.  I haven't been in the 230's since I got married in 2008 and while I should be happy, I am just "meh" about the weight loss.  I *am* disappointed that I only lost 5 pounds this week, I was hoping for a larger number, say 8-10 pounds.  With that being said, I am bloated and retaining water from my period and I haven't taken a poop in a few days, so perhaps that is screwing up a bigger weight loss number, say 8 pounds?  Grrrrr, Mother Nature, grrrrr!!!!!  Also, how stupid is this, since I keep thinking that I'm going to fail and gain the weight back (because that is what I am used to happening) I am not allowing myself to squee and jump up and down from excitement.  Yeah, I know, fucked up; something I have got to work on.
