The reason you’re feeling like that on weed is probably a mild panik attack, you should not use it if it makes you feel bad.
I know some people who do puke when coming up on MDMA, but most people don’t.
0.1G is a decent dose and as Nigboat said after about 1.5 hours if you can feel the buzz nicely and are enjoying your self you’ll be fine doing a little more if you so wish (you might not need to).
Have fun. 🙂
