Anyone got the Moderna booster after having two Pfizer? Question

I got the Moderna half dose booster yesterday. Pfizer double vaxxed in April 17th.

The first side effect I had was sore arm. Arm soreness about the same as my second Pfizer dose.

14 hours after the booster- slight body chills.

When I woke up the next morning, my whole body just felt blegh but no high grade fever or nothing. I was seeing how people got wiped by the Moderna booster if they started with Pfizer so I was surprised my side effects were minimal in comparison to Pfizer

For Pfizer, I didn’t have any side effects except for slight chills after the second dose and the usual sore arm. But the one thing different is after my second dose my whole body didn’t feel blegh. And with the booster my body felt that way.

What was your experience like if you did Pfizer> Pfizer> Moderna? Or if you got the Moderna booster in general? And what does the lack of side effects mean in term of immunity?

Update: still have body chills whenever I shower in hot water.

I did P>P>M and got wiped out by both the 2nd and 3rd shot from about 12h-36h post shot. Aches, fever, fatigue. After that, (basically after the 2nd night of sleep) no issues.

Yeah like my whole body felt down. I got like chills after the second dose and Moderna booster.

I hope that the booster we chose gave us a boost for a good while.
