I love scan bran!!
Maybe as you have only just started having it, just have it a couple of times per week and not 2 days in a row. Drink plenty and let it 'work' through your system before having another portion.
Fibre does have a tendency to bloat you as it swells but can affect some more than others......!!
It does the trick though
I got really bloated when i ate 5 a day and so now if i want to eat any scan bran i tend to stick with 2 a day and i get no bloating with eating just the 2 x
