plateau #1?
I'm sure it is just a stall! We are all lightweights and I think every single one of us thought "is this it" at one point or another. But all of us are at goal or well on our way! You can totally do this. If you can't work out, definitely keep your eating under control. Watch the carbs and sugars, and get lots of protein! I have to take Prilosec 2 times a day to keep acid under control.
Try not to let it get you down. I'm sure it is just a stall. I would watch your calorie intake at this time of year, however. I know it's hard, but if you want to keep losing you will have to resist the temptation to eat chocolate and other holiday goodies. I'm concerned about your Dad buying chocolate for you.
