I'm sorry I don't mean to belittle your post operative difficulties but I had a pleural effusion a few weeks after getting home from hospital. I increased my use of the Spirometer they gave me, it took 3 weeks and 3 more chest X-rays but it eventually cleared up without hospitalization. Also they told me from the beginning recovery would be 6 to 8 weeks. Getting extra sleep is an important part too. Not sure how much caffeine you consume but I have found too much or too little really has a huge effect on my energy levels now. Things like that you can only figure out for yourself by trial and error. Never under estimate the power of taking charge of your own health. I know it's difficult when you feel like crap but in the end it's the one thing you can and must do for yourself.
