kimik and sarge,

There is no way to get around the need for continuous quiet rest for the brain to recover. Taking time to recharge does not make up for the stress that caused the need to recharge.

The brain needs long terms of stress free quiet rest. Resting on the weekends will not be much help. As others have commented, taking time off from school is a good idea.

Taking stimulants like Ritalin or Adderal may provide temporary cognitive functions but do not help with recovery. They may stop recovery or even be detrimental to the point of making your condition worse. Same goes for caffeine.
