Micha,
Hello and I am wondering who told you to stop it due to addiction. You are not using a heavy dose and 2-3 times a week is not going to drive you to addiction IMO. Yes people do become addicted to the benzos but it takes time, using it regularly and/or misusing it.
If you need it and it works, I would use it as prescribed. If you need to go off it there are some very good Slow weaning processes avaialable to follow so you don't go through severe withdrawal. I hope this decreases your fears. Gentle Hugs to you.
