Did you test your glucose level? A few weeks ago i had similar feelings.. shaky, feeling sick and weak and generally panicking. I tested my blood glucose levels at 5.3 where normally I'd been around 10. I retested 10 mins later at 5.6. When I spoke to my DN.. she said that I'd probably had a rapid drop in levels and that the body sometimes goes into panic mode when this happens even though my readings were still at a safe level. Just to add 14 units of Novorapid would be a lot for me I only take 4 units as advised by my nurse. Hope this post helps.
