lower fasting glucose

Dr Ramsetty thank you for your recent response on lowering fasting glucose.  You said you needed more info.  I take metformin 500mg with breakfast & dinner.  Then at bedtime I take Januvia 100mg.  I eat a low glycemic diet and exercise. Sometimes I eat a snack at bedtime, sometimes I don't, and still cannot get my morning fasting numbers lower than 117 to 130.  I would like to get the 100's.  During the day I test twice and my numbers are 94-120. Also would you know why I continue to lose weight?  I've been diagnosed with diabetes in the last two months but when initially diagnosed I had already lost about 20 pounds in 2 weeks and now, a month later, I have lost 7pds more in 2wks. Thank you for all your help - I greatly appreciate it.
