mrs-p this will only last a couple of days, really!
Apart from the cold, I sometime where gloves in doors as I am that cold, BUT, the rest will go, by the weekend you will feel fantastic and full of energy.
I have found that having the packs hot warms me up quite a bit. Peppermint tea, and the water flavours (when you get them) are also nice hot.
I have been having half vanilla packs and making them into lattes throughout the day.
And when you go for your first pop in you will be amazed that you have lost already.
