thats one of the reasons i dont use them... so fucking annoying... many are needed to be pinned 3 x a day IF YOU WANT TO RUN THEM RIGHT... some will say you dont have to, and thats fine, but you dont get full benefits without dosing properly and if im doing something, its all or nothing... i dont do things that dont give the best results... thats just flat out fucking stupid... for the pain in the ass and what you actually get, for me, i dont go near them... its too annoying and inconvenient... also, accommodating how you eat around them really sucks... i hate all of the process...
