vnmum - sorry to hear that, but good that he has been to the doctor. My DH suffers from this occasionally but refuses point blank to do anything other than self-medicate with alcohol 
MrsHP - definitely not me!
nappyaddict - I have no idea re Feta cheese! Most cheese is carb-free (other than processed stuff), so I don't know what's involved in making Feta that adds the carbs. But it's still very low in carbs - according to weightlossresources it's only 1 g carbs per 100g.
Ewan - I try and make sure I usually have stuff like chicken/pork chop/low carb sausages or something to hand. But have been known to just have boiled eggs or yoghurt!
I had a difficult day yesterday - down to Devon for a client meeting, horribly delayed on the train, no time to eat when there, rushed back to station, no food shop at Exeter selling anything vaguely low carb, and the train back had no onboard chef as we went back a different route (had been cooked a mushroom and cheese omelette on the way down), so ended up eating a sandwich
.
Hopefully not too much damage. Was good for the rest of the evening, and drank gin rather than wine in an effort to keep the carbs down
