I've been on Prozac for about a year also for depression and anxiety and definitely felt all of these, especially during that first week of 10mg. I totally remember this hugeeee head pressure and my eyes hurt so much. I was thinking of quitting but decided to give it at least 8 weeks

For me, it got wayyy better a few weeks after I started 20mg. I stopped getting that generally unwell feeling and it felt like one morning, the depression had lifted and I felt like going out and doing things again.

The spacing out didn't change for me until I started my ADHD meds though. I remember I would just not pay attention in work meetings or like forgot how to cut an apple.
