I don't think the people above are right. If you really want to get lucid you should put in all the effort you can. If you get tired, so be it, but now that you have all this energy you might as well use it because maybe it won't happen again.

Sometimes I feel these surges of energy. In strength training, endurance training or violin playing. Sometimes I go through insane training or practice sessions that are absolutely impossible to put into a schedule. Because of the incredible mentol effort it requires. So go for it man. Use the energy while you have it. Moments like this are very rare.
