Hey Mollo,
I am currently on lipotrim and I'm about 3 weeks in.
I've found it very hard but doable. The shakes make it easy for you to make your mind up what to have for tea, but it can be a bit sad when visiting a shop and remembering the only thing you could buy is a water or a coffee.
I have found not having physical food hard too which I thought I would be ok with haha.
If you have any questions, I am happy to reply.
