I'm not actually physically seeing her, cos she lives in Middlewich (which is quite a way from me) so what I am doing is weighing myself in Boots in Broughton Park and letting her know the details, then she will counsell me via email & phone calls, until I need to see her physically. She comes to chester quite often so she will drop off supplies.. so it will hopefully work well... but you see my CB is like yours, I keep thinking bugger it, I am getting weighed for my re-start tomorrow, so eat like a pig tonight, just baked another fruit scone round and it smells delicious...hhhmmmm
A wedding is different, hopefully you will be served mainly protein with veg etc so you shouldn't be too bad, just don't forget the drink might go to your head, so probably try not to drink until the toast (after the food) otherwise you may be poorly and space it out with glasses of iced water (served in a wine glass!!)...
Love
