Confused about lowering meds.....

Dear all,
I have been quite successful since starting to lo-carb - a1c down from 7.7 in January to 5.2 in june. Also have lost over 30lbs. So really chuffed with myself......

Trouble is I keep reading posts from other successful lo-carbers who manage to reduce their meds down and sometimes are able to give them up completely.

When I started to lo-carb, my meds were as follows:

72 units daily of Lantus
60-70 units daily of Novorapid
4 x 500mg Metformin.

I now take the following:

28 units of Lantus (split into 14 units in the morning and 14 at night)
38 units of Novorapid (2 x 14 units and 1 x 10)
4 x 500mg Metformin

The above levels are keeping my bs between 4.8 and 6.0 fasting and between 5.0 and 6.3 after meals. I am eating no more than 30-40gm of carbs a day. i have tried to cut the insulin down but this just pushes my bs up. I now feel that I am failing by not being able to cut it down more. Can anyone please advise me if I am doing something wrong? Also, the weight loss has plateaued at the moment - I am ok with this as I was expecting this to happen - and will hopefully kick start it again when I increase the exercise.

Thanks in advance for any advise........

Thanks for your advise, will up the exercise and see what happens, and will definitely try and stop beating myself up about the insulin............... trouble is, now I have got my a1c to 5.2, I really want to keep it there!!!
Have a good one everyubody....
