oh jeez last year I went to boots for the ketos, I didn't realize it was a big thing and stupidily told the pharmacist that I was on a vlcd and wanted to see if I was on ketosis yet!...lol, I got near half an hr of lectures abt how dangerous,.... blah, blah blah these diets were.... in the end I left without it, went to another chemist this time wiser and said I was buying for my bf who was diabetic, no other q's were asked...lol.
