I'm drinking at least 4-5 litres of water a day, up through the night on the toilet which drives me insane!
That's a lot of water. You might want to check with your GP/pharmacist that you're not overdoing it on the water side.
Yeah the pic of 1lb of fat is revolting, i'll have to keep it in my head that i've lost 6 of them!!
Technically, no, maybe not. In week one, you typically lose glycogen and water. Fat burning typically doesn't begin until week two.
It's important to make that distinction, because when you come to the end of the lipotrim program, you have to go onto a refeeding schedule. This will build your bodies glycogen stores back to a reasonable level. If you don't do the refeed properly, you'll run the risk of piling on the glycogen, and glycogen can hold up to five times its weight in water.
People who come off of Lipotrim without doing a refeed can therefore put on about a stone in a week, if they're not careful.
If this isn't clear, ask your GP/pharmacist about it some more, or rewatch the DVD that comes with the program. It's also available to watch/download online.

Added : I see from previous posts of yours that you were on Slimming World towards the end of last year? It's possible that while on S/W you already depleted your glycogen stores.
If that's the case, then your "first" weeks weigh in with Lipotrim *would* in fact be fat burning. In which case, yes, you lost 6lbs of fat (so well done).
