Hello doctor, i've been waking up drench in sweat lately, it's not every night, but the last two have been this way. my room is moderate in temperature, and i typically sleep with 2-3 light blankets while only wearing long johns or boxers. what's up?

Night sweats: Night sweats generally are a sign of fever, with the temperature falling during the night. There are many possible causes. If this continues for more than a few days, start taking your temperature 3-4 times a day and recording the results. If you have fever (or even if all temps are normal), contact your doctor and bring along your temperature records.
