That's great you've gained 10 pounds! I remember you saying something about thyroid issues. One thing I will say with B vitamins is that methylated ones are the best quality. Ones that are made with folic acid and other types of acid are synthetic. They work, sort of but methylated ones are the ones that are best bio-available. They aren't super expensive either, you just have to look up specifically methylated and you'll get lots of results!
Gag reflexes are lame LOL thankfully I don't have one that's overly annoying and I can take these horse pills pretty consistently without an issue but every few weeks I have a night where I have to drink a LOT of water to get the shit down!
