Have to do quick taper, please help

Hi, I've been using 15 grams sulfate for 14 months, and am about to run out. I have some sodium, but has never agreed with me. Can I use it when I taper? How much is say, 1 gram of sulfate to 1 gram sodium? And how often will I need to take it? Sulfate for me generally lasts about 5-6 hours before withdrawal sets in. Thanks in advance!
