Honestly I think it's great it didn't happen until you were ten months out, you are doing things right. The feeling is horrible. It will very likely happen again and it's a reminder of how not to eat. I'm over seven years out and that would still make me very, very sick. My restriction never lessened, but I used that first year to make a lot of changes. You're doing great! Keep it up and you'll be at goal soon if you aren't there yet.
