There are multiple ways of managing stress: Healthy diet (4+ servings of fruit/veg a day) Supplements (Vitamin B2 works well) Exercise (1-3 times a week works) Mind-numbing hobbies (sometimes games can be stressful too) Do something you are passionate about Take a vacation (preferably a week or longer) Mindful meditation
In the long run, the most effective way of beating stress is to lead a balanced life. Sometimes it's neccessary to say 'no' to maintain this balance.
Best of luck!
