So yeah. Rehab. The ladies are nurses complaining about the drug problem in the area ("the fearsome excavation", c.f. "the ditch in the valley").
"Frozen rain" is methadone, vs. the "Pina Colada", i.e. the real thing. He's in rehab, lamenting his circumstances, and remembering how it all started and wanting to go back to when he had "bad sneakers", starting out in NY, etc.
Of course, the good ol' days - when he still had a "large sum of money to spend" - is why he ended up getting popped (i.e. he couldn't "beat the heat") and landed in rehab. Thing is - he knows he's killing himself. He sees the "ditch" out in LA that's being dug for him by the drugs, he hears about it from the nurses, but all he can think about is getting back out there.
