Had a couple of days without #ADHD meds as I reset my sleep medication and times (summer holidays mean I can sleep with my actual circadian rhythm rather than taking a boat load of melatonin to try and shift it to match 'society').
And boy oh boy does it make a difference restarting them again. I suppose that even having taken them for years being unmedicated still feels my 'default' state from the decades I was undiagnosed - so stopping feels a drag but normal. Restarting after a break is kind of magical.
