lee_bee, I am in exactly the same boat so I have no advice sorry but I hope someone else knows.

I lost 10kg on TF & then had to stop when I found out I was PG, DD2 is 8 months now & I'm hanging to get back on it - you're right the shakes are so convenient, with work & kids stuff etc I really struggle with breakfast & lunch, I would be happy to do that bit alone IYKWIM.

Anyway hopefully someone will be able to shed some light
