So i've been on SW for one whole week. Had picked my weigh in day to be Sunday. I had been sporadically weighing myself all week as I got curious. Yesterday, I was 3lbs down. Over the weekend, I had a night out on Friday where I was drinking bottles of Heineken. I ate very little that day and had no syns until my beer. I had also stored up lots of syns during the week. I was sick at the end of the night.. (ive turned into a bit of a lightweight). Then yesterday, I had a chinese take away but I ordered the healthiest thing I could find and had it with boiled rice. I'm due my period today but no sign just yet. Imagine my surprise when I got on the scales this morning and i'm now back to where I started. I'm at exactly the same weight as last Sunday!!!! Is this weight gain just temporary due to the period and the big dinner last night? Or have I well and truly blown it? I have been exceptionally good all week. I have written down every morsel that's gone into my mouth. I've eaten mostly free foods and finish each day with an average of 9 syns that I haven't eaten. Jeez, if you can't even have a few beers (I only drink once a month btw) and the odd healthy take away, i'm not sure this is for me. Help!
