On this recording Sick-Feeling Blues, the clearest of the versions on youtube I think, the last two lines sound like:

  Yeah, you know I sit and got an aspirin(e)*, it was no good,
  Aww, but a B.C. ain't help for me


* aspirin pronounces as if it had a final e.

I've no idea what a BC might be, but possibly abbreviations for an aspirin brand.

I'm not completely certain about the first half of the last line; if I've got time later I'll try and process the audio a bit to see if there's anything better.
