I would also caution you about doing it without the proper protocol from personal experience(torment).
My story is the same, used rescue inhalers my whole life, along with nebulizers, steroids, you name it. So, all rescue inhalers are propelled with fluoride(fluorocarbons). They may have bromide too depending on which meds...
Long story short, I took a small dosage like this one, and felt on the brink of death for about 30 hours.
I did no supplements, no salt loading. Don't do it!
I'm now doing it with plenty of salt/borax (to neutralize all my fluoride overload) and feel MUCH better.
