You could try for halfway between the 170 dosage and the 230 dosage. It's not exact and different brands come in different dosages; it doesn't have to be accurate down to the closest 100 mg.
Thanks, right now I'm starting out with a small dosage and working up to the full dosage.
I also want to thank you for putting out a book like this. It's so hard to find literature focusing on libido issues for women who are pre-menapausal. Especially something that doesn't blame it all on psychological problems!
