Stopping Levemir

I have been diabetic type 1 for about 8 years now I was taking novarapid and lantus. Then the doctor referred me to a new diabetic nurse well she decided to change everything as my blood sugars were high 15 - 19. She put me on Levemir I had to take 7 units at 6pm and 7 Units at 6am (getting up especially to take it). I have been taking it for 5 weeks and all that time I have had extremely bad muscle cramps, upset stomach I also have Chrons disease. I am also falling asleep during the day I felt exhausted. It has been so bad the last 2 weeks that I cannot even walk upstairs had to move my bed downstairs. Anyway I have decided today to stop taking levemir can I just do this and go back on lantus. I cannot get hold of the diabetic nurse and im feeling extremely fed up with it all

I did email her to say I was feeling exhausted the first week of taking levemir and she said it possible cornavirus symptoms. I cannot stand the diabetic nurse she wants me to eat salad and veg having chrons disease and illestomy these are not good on my stomach. I shall take lantus tonight and see how I go thank you She thought levemir would be good for me. Diabetic nurses seem to want eveyone to go on levemir I also have aspergers and hate change
