Actually I was pleased they allowed me to stay because I agree its important I get my head round this, but I also think its more important that he gets a grip on what he's eating.
For example, yesterday he finished work early because he was going to a meeting at 7.30 where there would be a buffet. He said he wanted to eat first at home so he wouldn't want to tuck in ..... so I opened a SW chicken and black bean frozen meal and cooked some of that slim rice. We had sugar free orange jelly and some squirty cream (3 dessertspoons).
I wasn't hungry so left mine till later. When I came back later to get mine, he'd eaten the lot but its syn free anyway so I thought it would be OK. (I had an omelette with cheese). I said that if he felt silly not eating the buffet just to help himself to a huge plateful of lettuce and salads without dressing, and pick at it with a fork.
This morning I actually asked him what he'd had, and after a bit of woffeling he said he's had 'a few chips, a small piece of quiche and a quarter of a pork pie'.

I rest my case!
