Warfarin Sodium and calves

My second run in with a blood clot resulted in passing out on my way to pick up my 8 yr old daughter and being rushed to the ER because of a PE (near death), I'm thankful to be alive however (no reason for PE and being on coumadin for the rest of my life) I feel so tired now, I don't want to go to work, I can't concentrate, I suffer from dizzy spells, I'm always hungry (weight gain), nausea sometimes. before passing out I was working out, doing Taebo, the balance ball thing, walking. Now I feel like I'm and old woman. I'm 32 yrs old and taking #5 coumadin and I feel so bad the majority of the time and yes the doctors say "it's shouldn't be the coumadin" but I think it is my whole world has changed and I'm just trying to get back to being the fun, outgoing, active me. I miss myself so much, its like I'm depressed. I MISS MYSELF.
