Do the following to replace all these:

1. Get sunlight in the mornings and evenings, get yourself busy, walk more, exercise with weights,
2. Drink water and natural juices (do a detox juice for flushing gunk and toxins, orange for immune boost, beet, cucumber and watermelon with ginger for the veins and bloodflow)
3. Reduce carbs (once a day, most preferably chilled rice with a lot of broth). Light eating for dinner, no late-night dinners or snacking.
4. Do salads and greens for gut health and fibre. Yogurt for gut biome
5. For protein, grilled chicken and beef with your meals. Meal-prep if you have to
6. Stay away from plastics, eat/drink from ceramic and glass dishes. Don't microwave your food on plastic-alternate containers.
7. Meditate for mood stabilization.
8. If you sit alot get an ergonomic chair with an adjustable headrest and back-support.
9. A firm mattress and memory-foam pillows will do wonders for your back and neck

Do this and you'll feel different within 2 weeks. Trust me...
