Warfarin Sodium and feelings

I had a PE 2 weeks ago,ended with cloths in both lungs,had injections for first week,now just on warafin 10mg daily.Only yesterday I thought I was going to black out,like a huge rush thru my body,and always feel light headed,like most the doctor said these are not side effects of warafin,but prior to taking warafin I never had dizzy spells.Just like to thank all you people for sharing your thoughts,as I feel now that at 42 I have to live like an 80yr old,and its comforting to know im not the only one.

Been taking it for a year now. I have become forgetful, arthritis pain has worsened, now so tired and foggy brained it came to the point of having to quit my job as I was unable to concentrate. And am now applying for disability. Have been without the medicine for 5 days now and finding it hard to sleep and having creepy crawly feelings on my skin. Has anyone heard that this is a aditictive drug? Because it sure feels like withdrawals to me. Still have my hair...thank god for small favors!
