Good for you! BTW, your dose is 112.5 mg, not grams :)
You're at a good dose for staying stable. If I recall right, Dr. Abraham took 100 mg, so you're in good company.
I think those of us who've taken more have our reasons. For instance, my first level of clearing was at 150 mg, when I "revisited" a very dark time in my life.
Do you need such an experience? Not necessarily. Consider staying exactly where you are. If later you need an adjustment, your body will give you a sign, which you will then have to interpret and probably do some research on, but you'll figure it out :)
