hi sorry its gona sound gross but. when i went to the chemist for my weeks supply he said i only have the Chocolate and the vanilla so i said ok and took both then when i got home i tried the vanilla and it is disgusting the chocolate is lovely. any way ran out of chocolate yesterday so i had to have some vanilla and guess what it make me sick litterally so i needed to take another last night so i rang lipotrim and explained it all to a DR (someone American ) and he said it was fine to have a pint of skimmed milk instead on the shake as it is what the shake is and has about the same amount of viatmins. so i suppose that means you can possibly substitute a shake for a drink to make them last as long also i an in kenosis and have had two pints of milk because i have my first weigh in today so i wanst having another vanilla and i am still in kenosis
