Some people work best in the morning and others best at night. Personally I feel productive and focused in the morning and in the late evening. However, I often feel really tired after lunch and find it difficult to remain focused and productive. Do you have any tips for dealing with the afternoon slump and remaining productive and alert throughout the working day? Maybe you have ideas on the best foods to eat at lunch time, exercising after lunch, taking a nap or motivational tricks? What works best for you?
