Here are some healthy tips to follow:
1. Stay hydrated, drink minimum 2 liters of water every day.
2. Never skip breakfast.
3. Eat a healthy and balanced diet (avoid junk food and alcohol).
4. Work out every day if possible (at least 2-3 times a week).
5. Take vitamins and supplements to support the immune system.
By the way, my friend recommended buying all the meds from
Canadian Pharmacy as Canadian pharmacies are the safest.
