Room-tilting spells when I stand up lately

Three years here, so I know this place runs on trends and nerves. For the last ten days or so I’ve had a few moments where standing from my desk makes the room do a slow tilt. Not spinning, not passing out — just a two-second lag. I’m 14 months into this journey and down about 58 lbs, and my habits have shifted a lot: less salt on food, more coffee, sometimes only 40 oz of water by 4 p.m. I remember an old thread about electrolytes and morning caffeine, and I’m realizing I never tracked timing of these spells. Yesterday’s was right after a long meeting where I barely drank anything. I’m not looking for a diagnosis or a protocol, just curious how others log this stuff. Do you note meals, fluids, sleep, position changes, or just mention it at your next appointment?
