Thank you so much for your kind advice. My english is not perfect, sorry. I took only one redbull in the morning on empty stomac. sometimes months ago two. supplementation b vitamines benerva and becozym. I live in switzerland, may be different names. I was always a lightwight woman, but in the last half year I lost 5 kilos and now my weight is only 46 kilos. I feel so week lost musclesmass and have severe pain of polyneuropathy in feet legs and hands. was on pregabalin 200mg but severe and terrible side effects, Im down now on 50mg but in pain. 68years old. it seems the docters here have no clue about how to handle megavitamin b6 syndrome. how does it go to push down this high level? I dont think with less vitamin b6 food. may be I will find more advice. thank you all for this webside and to all a good health
