Hi Jeff,
In theory, this is because of Liver Blood deficiency. The first thing to try is adding Dang Gui Shen to your protocol. Since we don't know if it will work, I'd hold off mixing it into the SMS, but if you do decide to do that, then I'd go with 20g per 100g of SMS
Otherwise, if you dose separately, you're looking to give about 20% of the dose of SMS you're using
