Hi Dee. This is going to sound very negative, but I'll add my two penn'orth...
I got the maintenance samples before my hols - to my taste, they were pretty awful! The orange creme and the chocolate were so sickly I couldn't finish them. The caramel bar (which I was really looking forward to) was incredibly hard and tough to bite through, very dry and tasteless and then stuck to my teeth horribly. I nibbled away at it off and on all day, but couldn't finish it either!
At least I can finish the summer fruit shake, but I don't like the texture - it's like eating froth all the way down! Next time I'll have to just stir it rather than using a whisk and see if that helps. The soup however is actually quite reasonable.
I got some of those two to bring away with me and I've just used one in place of a lunch on 3 or 4 occasions. I cannot for the life of me imagine having 2 or 3 of them a day...!
I also brought a load of the tfr shakes with me, intending to have them for breakfast, as I was used to. I can't take the vanilla in my coffee, because I found it too sweet (I've never liked sugar in coffee or tea) but I would always have a coffee, the vanilla shake and then another coffee. Bizarrely, since I've been eating again at lunch and dinner, I've not actually felt the need to have anything for breakfast other than the two coffees, with occasionally a bit of fruit just to nibble... Mind you, it probably helps that I'm having lie-ins and so I'm eating lunch only about 3 hours after I get up!
All in all, I'd say get the samples and try them yourself after you've re-fed for xmas. Then you can better decide if it will suit you or if you'd be better going on tfr again. Hey - maybe you won't even need to - you might carry on losing when you re-feed anyway (if you can avoid too much cider

).
