The topic at hand is about dealing with work-related fatigue and brain fog, especially for someone who is new to living with an ostomy. This person is experiencing severe tiredness and mental cloudiness during the workday, making it difficult to function effectively. They are seeking practical advice from others who have faced similar challenges, recognizing that different jobs may present unique obstacles.

Here are some helpful suggestions and insights:

1. Comprehensive Blood Work:
- It's important to get a full blood test to check levels of iron, B-12, copper, electrolytes, and red blood cells. If necessary, ask for an occult stool test.
- Fatigue might be a sign of deficiencies in iron, B-12, or copper, or it could indicate more serious conditions like bowel cancer. If initial tests don't reveal anything, push for further investigation.

2. Iron Management:
- Low iron can lead to extreme tiredness. Some people have needed iron infusions or blood transfusions.
- Consuming foods or drinks rich in vitamin C, like orange juice, can help your body absorb iron better.

3. Electrolyte and Hydration Support:
- Check your electrolyte levels. Drinking electrolyte water regularly can help if mild dehydration is contributing to your fatigue.

4. Diet and Nutrition:
- While adhering to low-fiber restrictions, try to gradually include nutrient-rich, stoma-friendly fruits and vegetables to boost your energy.
- Make sure your meals are balanced and consider taking supplements, such as chelated copper, if you're deficient.

5. Sleep and Scheduling:
- Aim for a consistent sleep routine of about 8 hours each night.
- Break your workday into smaller segments and plan for rest breaks when possible.
- If your job is physically demanding, discuss possible duty or schedule adjustments with your employer.

6. Lifestyle Adjustments and Coping Strategies:
- Accept and adapt to your current energy levels by modifying leisure activities, pacing yourself, and managing your workload.
- Meditation and stress-management techniques can be beneficial, especially if fatigue is related to seasonal changes, immunosuppression, or mood.
- Staying mentally and physically active, such as taking up a hobby like carpentry, can help combat afternoon lethargy.

7. Medical Follow-Up:
- Work closely with attentive healthcare providers. A thorough, experienced clinician can sometimes uncover issues that others might miss, such as a copper deficiency.
- Don't accept persistent fatigue as "normal." Keep seeking answers until the issue is resolved.
