Hi Dimrie,
I haven't tried making a hot slimfast drink but I would think it is do-able! I did it when I was on lipotrim.
You could try mixing (if using the powder) the shake with much less cold water and then adding hot water to it.Let us know how you get on
hi dimrie, i love hot chocolate so i buy the options ones they come in loads of different flavours, 33 cals mixed up with hot water and they're only 25p
