If i take 10 sleeping pills every 4 hrs each and everyday what will possiblely happen?

Medicine overdose: This regimen sounds dangerous. 10 pills of any kind every four hours is an excessive amount. Medicines such as tylenol (acetaminophen) PM or benadryl may be toxic in these amounts and cause damage to your liver. If you feel it is necessary to use 60 pills daily to help you sleep please cut back on your medicines and see a sleep specialist.
