Convalescence after pulmonary embolism?

I had pe last week, and I was wondering how long the convalescence should be. I was in the hopsital emergency room for 2 days and as soon as the blood clot was gone, they told me to go home and didn't give me any time off from work. I took Monday off and today I tried going to work but ended finishing the day at lunchtime, I was so exhausted that I slept all afternoon afterwards. Is this normal? Has anyone every had PE?
