Does deca make you feel tired?

Running 400mg/test and 300 mg/deca - my third week ended today, but I have been feeling really drowsy this whole cycle. I wasn't sure if it might be caused by the anti-depressant, but I have heard from others that deca made them feel lethargic and tired throughout the day as well. If so, is there any way to combat this? Does anyone think that maybe I should stop running the deca a couple weeks early?

What's worse is that there are sleeping problems coupled with the daily lethargy and drowsiness!
