i am very concerned about the fact that you are taking very high doses of an over-the-counter medication and not following the instructions on the package. because it is over the counter it is only safe and effective when used properly. this is very risky and can lead to problems (like toxicity in your system that can cause cardiac problems seizure coma and even death) and including the fact that you probably developed a tolerance to the medicine because they are not meant for long-term use. as you continued to increase the dose you also put yourself at risk for developing "rebound insomnia " which means you get insomnia that is worse in nature. you should stop using this medication and should make an appointment with your doctor or healthcare provider and advise them of your misuse of this medication.
