I went to Doc today and he switched me over from 70/30 mix pen to just Lantus pen in PM to start. He said I'm still in honeymoon stage and to start with 2 units and check BG's often. Then if I have high numbers after meals to let him know and I will then go on Humalog pen also. Just concerned as I'm newbie and was wondering if I should wake up every so often and check Bg's this first night? Was having too many lows on 70/30 mix pen.
