Hi there ~
I understand your concerns. There is a good chance of death if you take a huge dose of sleeping pills. I believe that you may have a chance of respiratory depression
with the overuse of sleeping pills. It may also be good to be aware of the fact that sleeping pills usually affect your sleep architecture and do not give you a refreshed sleep in the long run. They may be useful for about a month or two. I advise you to take the medications as instructed.
I hope this helps. Take care and have a lovely day!
