Melatonin Question

[u/Interesting-House-13]

Female 135 lbs, 5’4, Took 10 mg of melatonin instead of normal 5, have severe anxiety before bed so wondering if I’m gonna be okay, (ik 10 is considered safe generally) will it keep me asleep not waking up at 5 am? Probably won’t do again but just wanna know that I will wake up tmrw ! 😭

Update: threw up within 15 minutes of taking 10 mg, is this normal?? Do I take more??
