I would see a good physician. He/she would have to get a solid medical and psychological history to eliminate any conditions that might be the cause. Usually, if I'm sleep deprived for a day or two, my body makes up for it by giving me a longer, deeper sleep. The sleep deprivation you describe can be dangerous. You wouldn't want to operate a motor vehicle, for example. There may be other medications you're taking that are causing your insomnia. Or it may be a physical condition. I'm just guessing, of course. I don't want to alarm you but urge consultation with a doctor who will spend some time getting to the root cause of your insomnia. I would walk away from anyone who throws you sleeping pills. They only work for short periods of time as you quickly build a tolerance. They also interfere with the deep stage of sleep known as rapid eye movement. Paradoxically, they block the kind of revitalizing sleep that allows you to wake up refreshed. I would also stay away from melatonin. It is a complex hormone that has many risks despite its loyal following. I hope this helps.
