I went back to the hospital today, i am 32 weeks pregnant now. i was on 2 metformin twice a day and then increased it to 4 metformin a day but it didnt agree with me..now i have to take insulatart before i go to bed as well. i have been told to start with 6 units.. but i am so scare to take it after all the talk of having a hypo if it goes too low..is 6 units a low dose? i have read it is long lasting release over 24 hours..im just so scared of having a hypo in the night or something..i took my metformin after dinner and my blood sugar is in range, so what if talking the insulin at bedtime will lower it even more?
