I have spent the last 35 years solving very difficult problems in semiconductor design.
Younger friends told me to be aware of a mental fog after the stab.
For 3 weeks after the stab, I thought I had lost my mind as I couldn’t even solve even simple problems.
All back to normal but my boss was so worried they put me on a less complex process.
Damn, I have that and I haven’t even had a shot!.................
My ex told me about “brain fog” too. She experienced it. She just went through the “vax rage” and her boyfriend kicked her out and took back the car he bought for her.
Some how I don’t think it has much ta-do about about her getting the vax.
