4th day - ate 3 crackers, have I ruined by water fasting?

I'm on my 4th day and it's been very hard so far. Very fatigued and sluggish and nauseous. On my second day I even had a fever of 102, I know that this is part of the detox, but how bad did I do by eating three saltine crackers (minus the saltine)lol this morning. I threw up on the way to work this morning and I had to do somthing to make it through the day. Have I ruined my water fasting? Tweet
