Should Celexa 10 mg be taken in the morning instead, since it is prescribed to reduce stress and anxiety and I do not have any issues with my sleep? Especially if its effects are most prominent in the first eight hours.

It is important to take Celexa at the same time every day, as it can cause drowsiness or insomnia. The medication may take 1 to 4 weeks to show effectiveness, and it takes around 35 hours for half of the medication to be eliminated from the body. Make sure to follow your doctor's instructions and take the medication regularly for best results.
