Feeling delirious/drunk after a day in the office?

I am waiting for my autism assessment and so can’t be 100% that this is autism-related, although I am quite certain it is.

I find myself becoming increasingly exhausted after a whole day in a brightly-lit office, masking and being ‘bubbly’, chatting to colleagues, etc., so much so that at the end of the day I almost feel drunk and can struggle with basic tasks.

Is this a common experience for those with ASD?
