stomach neuropathy

in addition to other question, my sugars have been CRAZY!!  Have been on 70/30 60 units twice daily for years and recently have had very low sugar so dropped insulin, (on my own ) and have been able to keep them down (most of the time) but after seeing Dr. was put on Lantus 10 units as long as sugars stay under 200 then increase next week by 2 units per day-my worry is that it will make my sugar go down TO LOW which is usually around 100 and I get really "shaky" so what now?
thanks again!
