Post op question

I’m a week post op. So I’m not concerned about it or anything but just wondering if it’s not uncommon. I can easily drink an oz of water over 2.5-4 minutes although they said it should last 5 min. I had my post op today and had the swallow study everything everything looks great but I think I’m drinking too quickly. Of course if I drink too fast it’s uncomfortable but 2.5-4 minutes I have no problem at all. Anyone else experience?
