Maybe fewer reps? If you’re doing twenty, go back to ten for awhile.
If you’re doing the footflick in movements 2 and 7, try doing it without the footflick. Go back to doing it as simple as possible until your body adapts to the energy of the morning.
Or, divvy up the movements. Do movement 1, then take a short break, then movement two and take another short break, and so on. Try to slowly transition to the morning’s energy by kinda relearning D&T.
But definitely give yourself a wide berth between what sets off the nausea/dizziness and upper body erratic energy.
Is it only happening when you’re practicing or does it happen leading up to practicing D&T in the morning?
Maybe also simply sit comfortably, or lie in bed before you get up, and visualize yourself doing the set. Either to prepare your body and transition it to practicing in the morning or as something instead of practice if the dizziness is occurring leading up to practice. Also maybe do this visualization throughout the day if you haven’t got time to practice or it is too much. Also try the visualizing of it before you go to bed. Really feel like you are practicing the movements while falling off to sleep, super relaxed.
