General question abt gallbladder polyp.

So i had few questions regarding a gb polyp in my usg yesterday, it showed 2.9mm polyp attached to the anterior wall of gallbladder. 1. Is this serious? 2. What food should I avoid? I anyway have been avoiding junk food since a long time. 3. Can I drink alcohol in moderation?(once or twice in 4-5 months), will it be safe? When i drink that too will be in moderation, maximum aroind 90ml. 4. I am avoiding fat, which fat to avoid, saturated or unsaturated as well? I was planning to take omega d3 tablets, will it affect the polyp? 5. At what interval should i repeat usg? I am confused about annually or half yearly, as my doctor said anually bt my frnd who's pursuing mbbs, said half yearly. 6. Can i take chicken(boiled), daily? As i workout in gym daily 7. Does this regress or go away on its own? Please help me. I am worried and unable to sleep because of this.
