I am trying to quit xanax i have been taking it for only 30-40 days starting with 2-3 mg / day ending with 10-15 a day

I know I have to taper because of seizure risk, but I'm not sure how many mg's to use, I took 5mg last night and I think that's too much, I was thinking of going to 2mg tonight, any experiencd advice is appreciated
