Exactly two weeks ago to the day, I had outpatient surgery on my left leg, from which I am presently recovering at home. For the last 5 days, I have stopped the narcotic pain pills, and have only been taking Extra Strength Tylenol. Actually, I have been trying to even wean myself from taking those pills, too. Would any of these things be contributing to the fact that for the last 3 days, I have had a constant lemony taste in my mouth? It is as if I were continually sucking on a lemon.
