Instructions on how to get Sludge Lung to register for achievement

How to make Sludge Lung resister correctly.

Pop a Radaway to lower your disease resistance by 50% then go into Belching Betty Mine without a mask to get Sludge Lung.
Immediately Server Hop. **apparently there is an internal timer that keeps you from getting another disease within a certain amount of time, so hopping servers resets the timer**
Go to Mama Dolce’s Food Processing plant and head Southwest about 50 yards to the “warehouse” looking building with scaffolding outside of it.
On the South side of the building, there is a doorway there with a mailbox and payphone outside. Right in the doorway is a trap, a Spike Strip. Run back and forth over it because traps can give you diseases. Once you get another disease from the strip, damn Sludge Lung should finally effing register for the challenge.
