Good morning F&FU,
I hope you have been successful in finding a pharmacy that does it near you. As everyone says, it does depend on where you live and whether you are male or female. Men have 4xwomen shakes so pay more. Here in Hampshire I pay £36 for womens LT.
Good luck, it really is the easiest diet to stick to as it is all or nothing. From what I gather it is similar to CD but without all the choices. I am a confirmed chocoholic but have just finished my 13th week on LT with about another 3 or 4 months ahead of me.
Take care and keep us up to date with your progress.
