<s>[INST] Sweating at night, smells like vinegar. Not making frequent bathroom visits though. Im 19, 5'10, about 270 pounds. My diet is pretty typical. Not a lot of fast food, but not a lot of healthy food. Have recently began drinking more water to try and reduce this from happening. Any thoughts? [/INST] Hi, You are reporting to have sweating at night, smelling like vinegar recently. At this point, if I was your caring doctor would advise to run further tests to determine the right cause:- thyroid function test- fasting blood sugar- measure your blood sugar if you wake up in the middle of the night sweating- neurological examinationFor the moment, I advise to continue drinking more water to keep hydrated and take oral OTC. Hope it was of help! </s>
