I did. Also read “One Second After”.
I think prepping might give you a headstart, but in 2-4 weeks, you’ll be as hosed as everyone else. Those with flashy shelters will be targets, initially. After a while, desperate gangs will start targeting ANY house where there might be supplies. Trusted neighbors banding together for common defense will have the best chance.
Prepping will probably keep you alive and well enough to handle just about any problem for a long enough time for society to generally recover from most things that could happen to it.
However, if we are so up the creek that there is no recovery for years on end, there isn’t enough prepping anybody, but the most elite, could do and thrive.
I would barely notice it for the first few months, except for the loss of the internet.
