Hiya Kaz :-)
Overcoming emotional eating is a real uphill struggle, isn't it? I do feel for you as I'm exactly the same - in the past I've been able to find a myriad of excuses for not exercising within my capabilities, or not eating properly, or just having a bit of this 'cos I'm tired, or a bit of that 'cos I'm upset, or a bit of the other because it's ok, I can start again tomorrow... and then I wonder why I'm not having any success!
What worked for me when I successfully took orlistat last year - and what I'm doing again now (as well as really upping my water intake to 1.5-2 litres a day) is just choosing things to make up a balanced diet that are less than 5% fat per 100g. So cheese (and I loooooooooooooooove cheese) gets swapped for extra light Philadelphia. That way I can have a sizeable blob on my jacket spud and not feel deprived. Low fat yoghurt, skimmed milk, low fat spread (new favourite is Lurpak lightest), small portions of complex carbs like rice and pasta, tuna, tomato based sauces, quorn etc. Whenever I shop now, if it's for me to eat, and it's more than 5% fat, it doesn't go in the basket. This is where the iron will comes in!
By sticking to this principle, I didn't have a single nasty side effect in the 3 months I took orlistat last year, and haven't so far this time.
I'm having to be iron-willed again as I've had to be out for dinner 3 nights in a row in my first week; two meals at friends' houses, and one curry night! If I hadn't been on the pills I would definitely have thought oh, s*d it, I'll be good again next week and stuffed my face - but by actually taking them it forces me to make sensible choices. I just had a little of everything offered for the main course (meat and pasta/veg/salad) and asked for fruit for pudding instead of the homemade fresh cream cakes, and at the curry house, didn't have poppadoms or nan, and just had a prawn/veg starter as my main course. I tend to make a joke out of things - one of my friends expressed surprise that I wasn't diving into the pud and said 'don't you like fresh cream cakes?' so I said I adored them - but so does my bottom! It feels like they're pleased that I'm doing something to try to help myself as we all want our friends to be happy, don't we? I'm clearly overweight, can't miss me at 16 stone, I'm afraid :-( so by being honest that I'm taking something to help me, and that means being extremely careful about what I eat, it helps me stick to it and I feel quietly encouraged and supported.
Heavens, what a ramble! I'll shut up now - keep posting and let us know how you're doing :-) x
