ps i just found today and bought a container of Epsom Salt here in bangkok--it was not easy to find-costs 1.25$ for what is like about 2-3 cups of the powder.
Epsom Salts is magnesium sulfate? right? sulfate is some sort of sulpher? I was told years ago i was allergic to bactrim ( an antibiotic-sulphur based i believe)--so i wonder if this Epsom Salts might cause an allergic reaction
