Trying molly alone at 15 - any advice?

For new years my parents are out and I have been wanting to try molly for ages. so im planning on taking half a pill at like 10-11pm and then taking more after like 30mins if it isnt hitting. and i've heard that you have to drink water so ill have water on me and gum.

but i've asked on other stuff and nobody has answered but do you like get kinda noisy off molly like would your jaw be really loud or somethingg like that, basically is it fine to take in your room without drawing attention to yourself?

also i am a heavy cart user, so when im awake im basically always high, should i lay off it the day before for a better experience?

or just any advice pls
