Oh yeah, lots of worse but if you think about the affect it has on your life its up there. And unless directly affected nobody knows shit.
No beer, chips, rice potatoes etc etc. No take out, no cake, burgers (well the bun). Literally takes a massive life change. Don't forget it can still kill you. Not directly but the damage it does causes secondary failures, heart disease, stroke, nerve damage even limb amputations.
You cannot 'just' drop carbs either, you have to moderate things like salt, teaspoon a day around 5-7 g added to your diet. Take that to the Jamie Oliver camp. Fluids too. Can't just load up the protein as that knackers your liver.
It really is a kick in the balls. I'm not one to go ott about stuff, I'm a very, "Well that sucks, how do we deal with it?" kind of person rather than blubber and whinge but I have to admit to a bit of a wobble.
