I'm roughly the same size as you, but slightly smaller. I'm 5'5" 100lb/45kg.

I did 25mg for 2 weeks, 50mg for 2 weeks, 100mg for 2 weeks, 150 for 2 weeks... (Basically I went up by 50mg every 2 weeks once I got to 50mg.) However, your pdoc's titration process isn't unheard of.

A therapeutic dose is between 200mg and 400mg. I'm at 300

Like Crazy Hitch, I've had positive results. No SJS rash.
