Hi Riri and Steve,
I read that you are on novorapid and levemir or lantus. I was diagnosed with type1 3 years and was soon put on novorapid and levemir and later lantus. Well, it was hell for me. I first noticed that while on the levemir my walking pace became very slow and I was 'dragging 'my feet and very tired/fatigued. I also felt in a drugged up state with a heavy head and sometimes light headed. My work is quite physical and I had to reduce my hours to 28 hours per week max. When I got home I'd be falling asleep between 6-7pm. Anyway, I came to realise that I couldn't take analogue or human insulins as they are genetically modified and I have within the last 3 week managed to get myself onto porcine insulin with ......to date.....great results. I'm feeking much better and everyone around me have noticed the improvements in me since changing to porcine insulin.
I think that you may need to speak to your DSN about trying porcine. However, be prepared to be fobbed off as it seems that many DSNs have NO experience of porcine insulins. I had to complain to my hospital trust after I'd been kept on analogue insulins then human insulins.
To get more info look up..tiredness and lantus or lantus problems or porcine users.. Read what these forums say.
GOOD LUCK.
