TBH I'd do some fasting basal checks and find out how your bg levels are behaving in the absence of food and bolus doses.
As for where to inject, you can also use your buttocks for your basal, take a look at the following which has some good advice on where to inject insulin:

Don't forget you can also get the input of your diabetes team, so I would get in contact with them and mention what you've said above, when you do ask if it's possible to change to an alternative basal insulin such as lantus or Trisiba as I mentioned earlier.
