Hi, Allyson~
Since you'll have only one bottle, I would recommend that you use a syringe to withdraw all of the Stadol from the bottle and place it into a clean, empty, very small glass bottle/vial which can be securely sealed. (make sure there is no Stadol in the tube running up to the sprayer lid) If you don't have anything like that, get a small bottle of generic saline nasal spray, empty it, and use it to store the Stadol. Then, draw up one cc of the Stadol from the storage bottle and return it to the original Stadal Nasal Spray bottle. Then fill the bottle with saline solution of the type I told you about (the kind used for rinsing contacts - absolutely plain saline). Put the sprayer lid back onto the bottle and make sure it is securely screwed down. Shake to mix well.

Use only ONE spray to begin with. Please make sure you are sitting down or lying down, as you don't know how you will react to this medication. Some people get nauseated, sweaty, and dizzy. However, absolutely nothing may happen to you in that regard. Then. . . wait. You will have to tailor your usage to yourself. For myself, I always diluted it at 4:1, so that I got four bottles of medicine (full up to the top) from one single bottle of undiluted medication. I used it for two years and a bit more, but never used it stronger than that. Be very careful how much you use and how often. It's a very small bottle, and it can be used up very quickly. I'm sure, at the price you paid for it, you don't want to waste it.
Good luck.
