When I first started on Celergen, I feel energetic but recently I feel tired and sleepy?
It is not uncommon to experience this. It means that you need to rest and your body is working on cell renewal. You will resume your energy level after proper rest. It is important to note that even though you may feel sleepy, it generally does not affect your energy level once you are awake because Celergen also regulates your sleeping patterns for a good night rest.
