Listen to your Mother.
She sounds like she's just looking out for you and your health. As cigar smokers we can easily see the benifits to the spirit and sanity that a simple cigar can offer but she will always see you as her baby. It's enough to concern her about you and your health. If all it takes is backing down a few sticks to take some worry from Mom's shoulders, it's well worth it.
There will be plenty of chances to catch up on missed sticks down the road.
P.s.
I'm not addicted either.
