Hey Mick, just taking it easy until Ramadan is over, then I'll be changing this up drastically, and will be writing a full article on my method and why I've come to the conclusions I have.
The milk is fine mate, but I believe I may need to boil it, as the method of pasteurisation sometimes causes more bloat than the sugar lactose itself for someone like me. If you're wondering why that is, it's because the process of pasteurisation (heating milk to around 70 degrees Celsius and holding it there for about 30 minutes), causes the amino acids to coagulate, making it extremely difficult for my stomach to handle..., no different to an egg white whence boiled and coagulated it in like manner. The western people (i.e. you), have been brought up on pasteurised milk, where the eastern people (me and nearly the whole of India), have been brought up on boiled milk, even when if we have access to raw milk, we still boil it. Different societies/different cultures, resulting in different internal microbiome (not better or worse Mick), just different to suite our environment. And yes, the bacteria you mum gives you when she delivered you and breast fed you, stays with you for life.
I've digressed I know, sorry about that.
