Gaining

Last year I was on meds and down to about 250ish pounds. I stopped the meds for a few reasons and omg the weight came piling on. Without really paying attention I've put back on around 40lbs. I was weighed in the doctors office at 290lbs today.
So what was your biggest accidental gain and your reaction to it?

My job shut down for a month 20 years ago. All my bills were taken care of so I relaxed and went away for the month.I was 130 pounds when we closed and when we reopened I was at 170. All I did was eat and drink while we were closed without thinking about how much I was eating. So when we reopened my coworkers said it looked like I enjoyed our break more then others due to my new belly I developed while relaxing.

So you gained 40lbs in a month! That's amazing
