Super spacey and distracted

I'm assuming this is normal, as my brain is essentially under construction and being rewired by Prozac...I'm heading into week 2 onboarding with 10 mg, and just feeling very spaced-out, like my brain is lagging. I'm happy, I'm energized, I just suppose this is thick brain fog? Will this ease off as the weeks go by and my brain adjusts to the medication?
