Thanks everyone. It feels like real change this time. I think age played a big part in it all.
My mum and my dad both have rare autoimmune diseases which has changed their lives in 50/60's. As I've been approaching 40 it's weighed heavier and heavier on my mind. I guess my options were to continue thinking sod it and carry on abusing my health knowing it may just go down the pan anyway, or change now, before it's too late and work on getting really healthy. Giving myself a fighting chance.
