For those of you who haven't got your 2nd covid shot yet I'd recommend chugging water that night hangover style. I woke up the next day very dehydrated w/ a nasty headache. Here's hoping it only lasts 1 day.
Felt nothing from the first one they're definitely putting extra 5g in the second dose.
might just be poor 5g reception in your area
but youve been a comrade by getting it, you dont lose points cos youve been lucky with the side effects, be glad of it
