You definitely need a better control of our sugar levels and I think changing the dose of day time insulin
and switching from HUMALOG MIX
to injection LANTUS
should help you better.However you may discuss about it with our treating doctor.
As far as feeling less sensations in leg and tongue are concerned,these seem to be due to peripheral neuropathy
caused by uncontrolled diabetes
.Proper control of sugar levels along with injections of VIT B 12 should help you in that.
Make sure that your sugar levels are controlled meticulously otherwise many other micro as well as macro vascular complications might set in besides peripheral neuropathy.
Control your diet and as far as weight is concerned,your main aim should be to remain in your required BMI.
