Sleeping too much

Hi Doctors,

I am male 29 from India. My problem is very excess sleeping.

It is difficult for me to get into sleeping, so usually induced by mastrabuting, but once I start sleep, i will sleep like as if I am dead. I wont be disturbed with any disturbance that haapens near me.

I need to sleep atleast 9 hrs contionusly, otherwise I will feel like I hadnt slept properly, and will start doze off.

Also its VERY HARD to getup, atleast will take an half hour attempt by my mom, by calling,shaking, pouring water etc.

Even if I got up, I will sit for atleast half an hour in bed,and will be highly irritated with an angry mood, not able to open the eyes, small headache, vomiting feeling etc also will be there.

I like to sleep late anad wakeup late, most of the times I reach office very late.

Somedays, I wakeup from my sleep between 5am and 6am, will lay alive for 8 to 10 min and will slide to very deep sleep till 9.30 am to 10 am.

I am very lazy to wake up in morning from my childhood days.

Also i feel very sleepy when am engaged with works which are not interesting for me, like learning, attending sessions, etc. I usually sleep most of the time in holidays.

This issue is greatly affecting my day to day activities. Please suggest a homeopathic remedy for me.
