Out of interest, if I may ask, did you start using Huel to fix a nutritional deficiency of some sort, or did you simply like the appeal? I've heard a fair few people say they feel generally healthier or 'better' after beginning it, which I find interesting.
I've been using Huel on-and-off for a few months — to replace my lunches for a few days each week, or when I don't fancy breakfast, or if I realise I haven't eaten enough calories in a day. I might start regularly replacing my breakfast with it, now.
