In my experience, time boxing helps to manage stressful work. By this I mean to keep strict hours, for example 9-12 with an hour lunch, then 13-18:00, and getting off exactly on time. Use lunch time to break up your day so that you mentally have progress rather than a uniform slog that you get if you eat at your desk. It also forces you to get stuff done asap and manage your work better. Outside of work, side projects helped me stay mentally fit and overall happy, energized. Combined with exercise that will help you perform at work over time.
