Congratulations on starting your NBE program, Jo. This will be the start of somethings big..hee hee. I like your idea to ramp up slowly, but I would take it one herb at a time. That way, you could even shorten up the intervals between increasing your PM dosage if all feels good, and if you then note any adverse reactions, it's easy to back off some.
Why did you choose SP? Many of the girls here question the efficacy of SP. I think Spearmint is a better choice either as a tea or in capsules.
Anyway, I'm excited for you. In a few weeks you will be feeling the effects of PM. OMG, it's something you will never forget!
