sritual warfare

So, I went to leave last night for a women's retreat that I had been looking forward too for a month and on the way there I stopped at Quizno's and got a sandwich and chips. When I got to the retreat place I ate my dinner and 15 min. Later my stomach started to hurt. At about 7:30-9:30 I spent in the bathroom throwing up and then dry heaving until all there was was bile. It was awful, so I had to call Brad for him to come get me and a friend stayed at the house for the kids. I dry heaved all the way home and then layed down on the arm chair with my heating pad on my stomach and slept until 3:30 then went upstairs and slept until 7:30am, and now my husband is going to take me back to the retreat because I feel much better. But, I know for a fact that was the Devil because all week long I've been saying how I need a break and I couldn't wait and he did not want me there last night. That is okay because he didn't win, I'm going back and I'm only eating toast!!
