Well done, I hope your bum isnt too sore lol.
Dont forget ifyou cant stomach any go straight back and exchange them. all the flavours are'nt brilliant but you will find your own tastes. If you listen to everyone elses tastes, ailments and side effects, you will start feeling them yourself all I can say is do it for you and you only and its quite enjoyable and it really is not that difficult....Its a great big mental game thats all and you will win, the results are just amazing, trust me.
Stay positive and Good Luck!
