Effect of Pre-operative Oral Hydration on Post-operative Pain and Nausea in Adults Undergoing Tonsillectomy

Tonsillectomy is commonly described as one of the most painful procedures that an adult can undergo. This study's aim is to evaluate if pre-operative oral hydration has an impact in reducing post-operative pain, nausea and vomiting, and opioid medication use after adult tonsillectomies. Participants will be randomized to a low, medium and high fluid intake groups and will record fluid intake on the day before surgery. After surgery, participants will record their pain and nausea at timepoints up to 7 days post-operative. Medication use will be recorded up to the first post-operative follow-up visit with their physician.
