Type 2 help

Hiall this Los my 1st post so please forgive me if got it wrong.. doh!
Last year I was diagnosed T2 iv always been fit and never over weight and healthy water.. tho if taken steroids for 10 years as i have a condition called sarcoidosis. Last year my b.s. was pretty much around 5- 8 each time I tested and was taking 33units of insulin in morning and 8 units at 5pm
However early this year they started to rise to 11 - 14 ish withno change in diet and has increasedslightly sometime going into the20s

So after seeing my nurse as ithought.. she said iv becomeinsulin resistant .. so she advisedthat I keep using the insulin withthe same units but start takingmetamorfin.. 500g after eveningmeal.. so after 2 nights my m s hasshot up to about 17 19 each time Itest.. no change in diet ..

Is this normal ???
She also suggested an injectiononce a week but iv totally forgotwhat its for..

So sorry the long story but anyinsite would greeeeat ... Shaneconfused xx
