Welcome to the forum. I will tag
@daisy1 as she has some good info she can post for people new to the forum.
When I am prescribed something new I check it out on the below website as it has very good info on side effects. However this US based site does not yet have info on Lyxumia because it is not yet approved by the US FDA. It was approved in the EU in 2013:

It's in the same family as Byetta and Victoza, so you may be able to find info about this type of drug by doing a search on the forums for those terms.
You can probably reduce your blood glucose levels (BGs) and lose weight by changing what you eat - lower carb, slightly higher fats. It may be possible to come off Lyxumia, then your other diabetes meds once your BGs are low enough for long enough.
I'm interested in learning about the links between the flu and diabetes, so I was wondering - was your flu diagnosed by your doctor and by any chance were tests done to say which strain of flu it was? People with diabetes are encouraged to get the flu vaccine every year because we are at greater risk of complications, so I was wondering if your doctor recommended this for you before or since? The most common flu strains circulating that year are in the vaccine, which gives about 80% protection against those strains. The vaccine can't protect against other strains but it is worth getting because of the strains it covers.
