Hi, my names steph, I'm 22 and need to lose about 3 stone- am setting slimming world tomorrow due to a meltdown in the dressing room finally making me realise I need to change! I've been looking at the menus and types of food and think I'll be able to stick at it, my only problem is I have a horrible addiction to red bull!! I know it's bad for me and this is probably what has put me the weight on! Is there anything else I can try that will give the caffeine kick I need??
