Oh snap, you and I had similar stats! I, too, ate ~300 calories a day (usually between 150-300 on this weird schedule I convinced myself wouldn't wreck my metabolism, kind of like the abc diet only my own version) and went from 140 to 90 in about 2 months in my latest stint with that bullshit. I never got sent to a hospital though, thank god, because my parents were convinced if I just ate a sandwich (my mother's words) I would be fine. Relapsing was such a bitch though.  I found that funny too! Like if you only ate ~coffee and an apple~ how the fuck did you have dinner? Did you count the calories you absorbed even if you purged? Because even if you throw it up immediately (or within 15 minutes) you still absorb ~20% of the calories and you have to count that shit and watch it. I would always, always count whatever I was binging on even if I was eating it right next to the toilet in preparation to throw it up.  TLDR This bitch be lyin' and we can all tell.
