I am one month post op. I have no issue drinking water. I believe I can drink an entire 16 ounce bottle with no discomfort. I don’t chug the entire bottle of water but I can finish it in one 15 minute sitting. Is this true for others? I have no discomfort or nausea. How much water is safe to drink at one time? I’d like to know your thoughts. I don’t plan on drinking a gallon but at times I will drink a water bottle then grab a Powerade and drink it in 4ths to keep my fluids going. Cheers :)
