After years of putting on weight even when I was trying to lose it, I've had my lightbulb moment. Now I need to use up all my leftover packs from all my half hearted attempts. Now I know we can use out of date packs because they don't really gout of date as such, eventually will lose flavour I know that. But I just wondered whether anyone has used out of date packs and what's the oldest date. I have some from 2012!
