I took some nyquil zzz last night and i think i mightve almost overdosed. what should i do?

Sleep medicines: Fllow the directions carefully. If you are not comfortable with the effect of nyquill zzz, then try a natural substance called melatonin. Its what yur brain uses to regulate your biological clock. In addition, try to keep to a consistant schedule of going to bed at a specific time. No caffeine after lunch. Turn off computer and tv about 1 hour before you get into bed.Try warmmilk before bed.
