So so tired!

Hiya all

So I'm sitting here at 2.42pm yawning like it's 10pm.

Since taking paroxetine for almost three weeks I have been so tired. Instead of going to sleep at 12-2am I am going to bed and falling asleep by 9-10pm. It's great in some cases because I can get a full night sleep and wake up at 7am like a normal human being but some days I get so tired that I cant go on. Now I am too tired to do any more work which is vitial to get into university.

Is this normal in paroxetine and in other meds? I was put straight on 20ml so I'm not sure if that's a factor.

Thank you.
