Quick update, so I went home gave him the lemon juice, a midnight snack and a benedryl and low and behold there was no backfiring (reverse sneezing) all night long! He was a little snotty this morning but after he ate and got his dose of lemon juice we have had no problems!!! He did get to come to work with me today just so I can keep an eye on him but he is doing soooo much better! Thanks again everyone for the tips!!!
