Hello & Welcome HCM,
I studied your case and want to know your age & weight. You are in fitness but you had taken a lot of Multi vitamin, is it advised by any doctor?What you have to do is just stop your all medication along with multi vitamin. And do some investigation Like Liver
function test and Kidney
function test. And take normal and light diet for a week.Hope so after investigation you can find your solution. Then after I can advise you further for related treatment.
thanks & Regards
