last few days I gain 300-400 g per day (0.66 to 0.88 pounds). I was 51.5 kg a month ago, and I am now 54.3 kg (113 pounds to 119.7). I also notice decreased urination, so it may be water retension; I also read that a study showed that under Benfotiamine + B6 + B12, 8% of people had weight gain. I moved from B6 to P5P about a month ago so I wonder if it may be the cause... I am not hungry. Any one on PR experienced this?
