Yeh, I made that mistake twice, sometimes, I just can't help it though =(. Taking after is definitely way less effective. I do have the theory though that if you are already in POIS, you can remove it by taking xan-pro the next day right before ejaculation. Not sure why that would work but I have a feeling it would clear away the previous POIS by giving you a flushed orgasm.
I quote this on purpose. Unfortunately, i had an NE before waking up and i could feel the hateful POIS symptoms growing on my body(bad digestion) and on my mind(feeling weird, brain fog increasing) .I usually get POIS symptoms very fast after the O. , and i could notice that something is going on on my head seconds after the Orgasm. So, frustrated, i decided to read this post again to find the quote in bold.
I ate a light breakfast, mostly fruits and compotes and then i decided to take 100 mg Niacin. This time was very different from yesterday. I got a very intense flush. My ears and neck were so red, and i can feel the hot everywhere. Some parts of my body and my arms turned red, too. Then i waited 50 minutes to have an Orgasm. All i can say is that Niacin is better than Fenugreek, better than Garlic and Goji Berries all combined. I feel no POIS, absolutely no brain fog(maybe i´m a little bit tired due to i didn´t sleep well) and i am waiting to make the lunch(one that has more than vegetables) to watch if the brain fog appears. I will update later.
