The change of diet hasn't been too much a shock to the system. Chris and I already didn't eat much meat, but now we are trying to cut it all out. She also wants to go vegan, I'm at least going to try and cut out dairy and eggs. I even started eating cereal with rice milk, it's not too bad after a you use it a week or so. You kind of have to get used to the texture, it's a bit grainy.
So go ahead and take your bets on how long it will last.... I'm enjoying it so far. Maybe it's just a mental thing but I already feel like I've got more energy, so hopefully this will all last.
