This topic is about finding effective ways to manage and control odor for ostomy users, especially when traditional methods like Hollister M9 deodorant drops aren't working as expected. Here are some helpful strategies and insights shared by others:

1. Adjusting M9 Usage:
- Some users find that Hollister M9 works better when used generously. Try adding a "good squeeze" of the drops to the pouch after every second or third emptying.

2. Alternative In-Pouch Deodorants:
- Consider using BBraun Ostomy Deodorant sachets, with 1–2 sachets per pouch.
- Try liquid drops like Na’scent, Safe and Simple, or Osto-Fresh, often using more than the recommended 12 drops.
- DEVKO deodorant tablets can be placed directly in the pouch.
- Experiment with a few drops of peppermint oil, mouthwash, or baking soda. Some have even tried TicTacs, Certs, baby powder, or carpet deodorizer.
- PooPourri can be sprayed into the bowl or pouch for added freshness.

3. Oral/Internal Odor Control:
- Devrom chewable tablets or Nullo chlorophyll tablets are mint-flavored and reportedly remove 90-100% of odor.
- Drinking cranberry juice or using Gas-X (simethicone) can help reduce odor-causing gas.
- Dietary tips include eating parsley, butter/oil, pineapple, mango, or peach, and avoiding strong-smelling foods like garlic and onions.
- Some have used "green herb" natural supplements for systemic deodorizing.

4. Toilet-Bowl & Room Freshening Tactics:
- Use "One Drop" or "Just a Drop" in the toilet before emptying to help control odor.
- Keep travel-size room or air sprays handy, such as those from Bath & Body Works.
- Carry a small bottle of peppermint oil or a standard air freshener in an emergency kit.

5. Product Clarification & Sourcing:
- Hollister M9 is an ostomy pouch deodorant available at medical-supply stores, which might be worth trying again with adjusted usage.

These strategies can help manage odor more effectively, providing peace of mind when using public or friends' bathrooms.
