Day33, Red alert, need input - time to stop?

Hello,

How do you know if it's a legitimate challenge or the body's last warning?

I'm on day 33. I feel overall good and clear. Yesterday, as usual, I swam and kept my regular routine.

However:

When I woke up from the couch earlier, I almost felt. I was way heavy and saw dark. It lasted for several seconds, until I sat down again.

I noticed in my writing earlier that i was exceptionally unclear, which indicates poor clarity.

My pulse is around 35 and that may explain the symptoms?

I wonder if I'm experiencing the red alert of "stop the fast"?
I can keep going, but I don't want to abuse or damage my body.

How do you know if it's a legitimate challenge or the body's last warning?

Thanks,
