Nice to hear you‘re doing well on Elvanse.
I noticed a weird feeling of emptiness/emotionlessness a few times, always in the early evening. This could be temporary anhedonia as the brain becomes desensitized from all that excess DOPA-Amin & Norepinephrine. Like your eyes having to adjust to the dark after looking into a bright light.
Light/noise sensitivity is up for me too, makes me wary of increasing beyond 30mg.
