rare cancer of lung

I was diagnosed on August 18, 2008 with adenocarcinoma with bac features when a biopsy and wedge resection were performed at Moffitt Cancer center. All they said was some live for years and others don't do so well. Their plans were to remove left upper lung but ct scan showed nodules on rl also and they were afraid if there were more they would just have to keep taking more lung. They could not get to the right side to biopsy as my heart was in the way so do not know if any were cancerous or not.
Had 3 taxol, carboplatin treatments, then pet scan. Pet scan showed no uptake. If there was more cancer it did not show up on pet before chemo and post surgery....I get deathly sick with the treatments and have had 4 now. The medicines do not help. They had told me at Moffitt, maybe all i would need was 4 treatments. I am wanting so bad to not have any more of them as I am now sick up to 2 weeks from each one that I have every 3 weeks. Had to go to er this week as doctor was afraid I had a pulmonary embolism. (didn't, thank goodness). Anyhow last pet does not show any uptake and the previous one before chemo stated highly unlikely that anything they saw on that pet was malignant but more like inflammation. Any advice will help as I am VERY seriously considering stopping. 75 years young and afraid this chemo is really damaging me a lot. What do you think?
