I was in a similar situation, although I got more than 3 hours of sleep. I don't think 3 hours of sleep per day is sustainable, you have to find another solution. Any work you do on 3 hours of sleep is probably not great anyway. I don't know your specific circumstances, but I used low dosage Armodafinil and Melatonin before with with success to get by with little sleep (didn't keep track, but I think at least 6 hours per day). If you are in the US you will need a prescription for Armodafinil, but if you explain your situtation to the doctor it is easy to get one. Armodafinil can be imported cheaply from India. Melatonin is over-the-counter. Hang in there and good luck!
