if you're getting married, you can use flexi syns! You say i'm going to use a certain amount of syns (i.e if you think you'll have 5 double whisky's work out the total syns) for everything you know you want to have then stick to that plan (i.e have the 5 drinks but stop there) it's for special occasions and i think your own wedding counts as a biggie! The flexi syns are there so you don't have to feel guilty about enjoying yourself
