Kati,can u not go and see your cdc to get some water flavourings and mix a mousse, tetras are pre made cartons which are very usefull to carry around with u incase u stay out longer than planned and cant get to make a shake.
If things get very bad later on then if u have an extra pack it is always better than eating.
Hope things ease up for u later,we can do this,it does get easier,just come online and chat to us till u r ready to go to bed,there is always some one around to chat 2.
Take care xx
