In my practice I use this type of DD for DM.
DM can be in 3 symptom forms.
1. Thirst, patient drink a lot of water - this type is upper burner dissorder.
2. Hunger, patient eats a lot and all time - this type is middle burner dissorder.
3. Urination, patient urinate a lot amounts - this type is lower burner dissorder.
usually I make a diagnosis at the first meeting and usually it at least 2 burners problem. I use acupuncture only, but is lot of herbal therapy can be used.
during the session of 10 meetings usually I get down sugar levels to less then 170 (most of patients came with peripheral sugar about 280-350). HBA1C gets down from 8-9 to 6-7 at 3 month. I start with 2 meetings per week for 4 weeks and the 1 per week.
Very important is to regulate diet, weight.
I didn't static evaluations but its looks like 70% is going well with this thinking.
