hi RooBee,
congrats on taking a massive step towards the rest of your life!!!
as everyone has said, the diet is hard, but totally worth it, just look at everyone's stats in their signatures.
the shakers i think are the best way to manage at work - i only ever use my shaker, work or home so i'm happy with it - getting a bit fancy now, like tom cruise in cocktail.
all you need is water so you should be ok travelling about. if i have to travel around i have my normal water supply with me, and also an extra litre for shake mixing.
best of luck with it, keep coming on here, it really helps!!
Sxxx
