Got my second dose the other day at 6 in the evening.

Sore arm that evening, a little tired but nothing crazy.

The whole next day I was very tired. Not the tired you get after you've been active - just bone tired, like my limbs felt heavy. All I wanted to do was lay down.

Sore arm but not as bad as the first time (like others have said I moved it around a little and didn't tense up as much.)

No other symptoms.

The next day I woke up and it was like a switch went back on - I felt fine.
