I want to recall what has happened to me with my last POIS episode(I had an O. 8 days ago)
I followed the usual steps: I took some fruit plus two fenugreek pills and then had the O. after intercourse.
Day 0 - 70% less POIS in the morning, just after the O. In the afternoon i ate some bread and had a significant increase of brain fog. I took some garlic cloves plus fenugreek that helped me to diminish to maybe 50% intensity of brain fog again.
Day 1- 60-70% less POIS again.
Day 2 - 80% less POIS.
Day 3,4- 90% less POIS, i could see the light at the end of the tunel.
Day 5 - No POIS symptoms, i felt really, really well.
Day 6- I ate an "english breakfast", and i realized that the sausage i was eating resulted in a POIS comeback. I felt terrible during that day due to an overwhelming Brain-fog, that i tried to combat with garlic+goji berries+fenugreek and it passed away on the night. This shocked me because i thought that POIS was definitely gone for this time.
