I had an O yesterday but did kegel stopped stimulation before full pump many contraction O and had 1 contraction, 20% of usual leak, felt a bit hot after but had less or no fatigue, brainfog, sluggishness, FOV/vision changes, lower voice volume/harder to understand pronunciation, today I'm ok, if brainfog is there then less than usual so it's something with many pump contraction full emission O that triggers most symptoms the strongest, my heartbeat's faster for 1 minute, feel blood moving in head and a tingly nerve feeling goes through body, limbs which is when muscle weakness/empty muscle feeling comes.
