that sounds a bit intense
i tried eating brewers yeast a few years back that shit will fucking give you a heart attack, its LOADED with b-vitamins i was getting like 10,000 percent of all the b-vitamins because i was taking a shitload of it. i didnt think it would fuck me up but it did, i nearly fell on my face in a grocery store i nearly blacked out it took everything in my power to keep myself together
Hmm that doesn't sound good
B-vitamin injections aren't like that....it's not that it amps you up like coffee, but it'll make you indefatigable. You'll feel like you can work & exercise forever.
Not to mention bc you're vegetarian you probably have low levels of vitamin b. I would really look into this for you
