Rainbow boa regurgitating- HELP!!

[Will0W783]

I have a yearling male Peruvian rainbow boa. He's been super healthy and I never had a problem with him until two weeks ago. I've had him since March. I had had a problem in the room with the timers on lights, and it got 87 degrees in the room, so it was around 87 or 88 in his cage. He had eaten three days earlier and regurgitated his undigested food item. I was very upset, but I fixed the lights and figured it would be fine. He puked on Tuesday. I fed him again the following Sunday night, and the temps were all fine. He puked again yesterday (Tuesday again). I checked his temps at various points during the day and it was between 83 and 85 degrees in his cage. I am a bit concerned about this regurgitation. My guess would be that he puked the first time because it got too hot, and then I didn't wait long enough before feeding him again, so he got sick again. Does anyone have any experience with rainbow boas puking? Anyone have any advice? I'm rather worried about the little guy.
