Have a checklist of "stupid" health maintenance stuff, not directly related to the problem at hand. Neglecting these may cause poor mental performance. Here are some example items:
- Be aware of how much you sleep, avoid chronic sleep deprivation,
- drink enough water that your urine is clear,
- watch out for blood sugar crashes from eating irregularly or eating refined sugar, these can mess your head,
- go running or to the gym, this will kick up your metabolism, and being in a better physical condition might provide more energy for mental work,
- try some basic dietary supplements, some omega-3 source, multivitamins and calcium seem to be commonly used
