Your Novomix, is a combination of Quick Acting insulin and Medium length insulin, designed to be injected 2x a day, with this type of insulin regime it's important to eat carbs regularly throught out the day otherwise you risk suffering an hypo...
At this point of time you really need to take your main guide of your diabetic team, as they can look at your blood glucose results and better advise adjusments, you do need to keep a diary of blood glucose levels, and foods that you've ate (and if you can work out the amount of carbs per meal) this will enable them to help even more..
Tip for the Novomix regime, is keep your carb count for each meal or snack the same, i.e if you eat 30g for breakfast stick with this, if you mid morning snack is 20g stick with this and so on..
As to Alcohol, I would avoid this for the moment until you've got your sorted with injecting and controling your blood glucose levels... The problem with alcohol is some like beer, larger etc contain carbs which will at first put up your Blood Glucose, but while your liver is processing the Alcohol it can not store any Glucogen (glucose that it's delivers into the blood stream 24/7) this can also be dumped in a emergency into the blood stream to bring blood sugar levels back up, usually via a glucogen Jab..
It takes on adverage around 1 hour to process one unit of Alochol until the Alcohol is cleared you will be at a very high risk of suffering a hypo with could be a very dangerous one, as these can be extremely difficult to get out of...
Tip for drinking..
Never drink alone, always ensure a friend is aware that you are taking insulin, and know the signs between a hypo and being drunk..
Avoid drinking too much, when you first start to reintroduce alcohol, start off with a small amount and check BG regular..
Always check BG regularly when you've drinking or have been drinking, and enusre good supply of hypos treatment is available to you..
