I've been T2 for about 10-11 years now, sooo. You take blood 4 times a day? are you eating 4 times a day? how many times a day do you medicate? You should medicate only when you eat, and try not to eat post 19:00, watch the alcohol intake as well (calories in a bottle)
Oh and a cautionary tale, a few years back my GP prescribed a daily injection (NOT insulin) of a product called Victoza, this is very good at keeping the glucose steady, BUT and here's the but long term use can have the side effect of causing pancreatitis, Just had a week in hospital with my third occurrence, in 5 years; I would suggest you question, with the GP, or better a diabetic specialist, the very rapid weight loss you started with, this would normally point towards T1, and some American research is now thinking there could be a T1.5, and possibly more sub species.....Oh and nice to see you again, still singing songs from the musicals?
