Fucking around with strep throat can cost your your life.
If you're determined to treat it yourself, I'd gargle with H2O2 (hydrogen peroxide) 3 percent, like Walmart sells for less than $1, about once per hour. spit it out and don't swollow, but a little won't hurt you too bad if you do.


You don't have time now, but Calvet (california vet supply) sells pharmaceutical grade antibiotics for about 20 bucks for a big bottle that everyone should order and keep on hand. they have keflex, amoxicillin and tetracycline for 20 to $25 for a bottle of 100 capsules. It's labeled bird stuff, but it's pharmaceutical grade.
