I was on Coumadin for a blood cloth I had last year(I originally started on 2.5mg and kept getting bumped up higher and higer as my PT/INR tests kept coming back).
I had most of the symptoms described here. The three worst being fatigue, memory loss and hair loss.
I remember constantly being tired on this medication. I had to go back to work after a few months and I remember not being able to lift much of anything and being extremely tired.
When I would take showers I remember running my hands through my fingers and literally pulling out clumps of hair. Each and every time. I thought I was going nuts.
The worst was the memory loss. I had severe short term memory loss like you wouldn't believe. I would be fine one minute and then space out and I literally could not remember what I had done the day before.
