hi carlos, not sure about an extra sicknote, i was diagnosed on a sat and back to work by the friday so just depends on circumstances i suppose. I work as a fencing contractor, which is pretty physical work with a lot of walking, i had a few hypos when i first started back to work and within a week i had to stop taking insulin in the morning and at lunch, 4 yrs on i still only inject for my evening meal and my long acting at night. Every individual case is different so just make sure you have gluco tabs or lucozade near to hand when you start back incase of hypos and hopefully after a couple of weeks you'll know how work affects your bloods, try not to stress too much!
