Yes, this is why I stopped filling my prescription two years ago. I excelled at work but it was damaging my relationship due to being so "zoned in" and at times robotic.
Yeah absolutely. It seems most people get only positive effects.
Must be personal neurochemistry/predisposition. The breaking point hit when my partner showed me a video she took where she called my name 8 times standing right next to me trying to get my attention, and I had no clue. I was so zoned into the screen.
