Making the Neti Pot solution, which is really just saline/salt water couldn't be much easier.
Put a cup or two of water into a pot and warm it up on the stove. (I use cold water that I warm on the stove because the water heater in my apartment is old and I don't really want to have water that has been in there all up in my brain.)
Once the water is warm, pour it into the Netti Pot and then grab your salt. Take about half a teaspoon of salt and put it into your water mixture. Stir it well.
Now you are ready to proceed. Find a sink, some privacy and read on.
