Does anyone else here get sleepy very easily when they read or watch television or a computer ?

No. It is the opposite for me. Reading a textbook makes me sleepy.

Yes. Happens to me all the time. I think it is because I’m active all day.. so when my body gets a chance to relax it goes all out.

There are lots of reasons why you might be tired all the time and fall asleep easily. Here is quite a nice article outlining some of the reasons. Do any look likely? Start by addressing those and see if that helps.
