I did have a profound experience with this supplement. The first few days I felt immensely grounded and my speech and articulation improved greatly. I took a week off then came back to it again. When I started again I took 2 capsules a day instead of one. This time I felt like Connor Mcgregor when I walked down the street and I became incredibly confident. I also had all this increased energy out of no where, it almost felt a bit manic in a way which scared me. Anyway this died down after a few days and now I don't feel much from it. I don't think it helped my POIS symptoms much but I need to test it properly.
What is weird is that I have tried eating lots of eggs everyday and have never felt anything. Maybe my brain has a hard converting the choline into acetylcholine.
