So all the good quality brands seem to have these crazy high doses, like from hundreds to tens of thousands over the daily value percentage.

Here's an example:

Thiamine (B1) 50 mg (4545 %*)

Riboflavin (B2) 10 mg (714 %*)

Niacin (B3) 65 mg (406 %*)

Pantothenic acid (B5) 100 mg (1667 %*)

Pyridoxal phosphate (B6) 12 mg (857 %*)

Biotin (B7) 352 µg (704 %*)

Methyl folate (B9) 455 µg (227 %*)

B12-vitamin (methyl- and adenosylcobalamin) 350 µg (14 000 %*)

Why is that? Is it more beneficial or harmful to use this much?

My body has been very relaxed these past two days and I feel I could sleep all day to the point that it's causing me anxiety because I don't feel normal.

Why could this happen and has people here experienced anything similar? I wasn't a weekly drinker but binge-drinking on weekends is my problem.
