Desvenlafaxine can sometimes cause insomnia, early morning awakening, restlessness, and increased alertness, especially during the first 1–2 weeks of treatment. Since you are consistently waking up about 4.5–5 hours after taking the tablet at night, the medication may be contributing to your sleep disturbance.
In such cases, many psychiatrists prefer morning dosing, as it may reduce sleep-related side effects while maintaining the therapeutic benefit.
However, any change in timing should be discussed with psychiatrist. Also, since you've been on the medication for only 5 days, some of these side effects may lessen as your body adjusts over the next couple of weeks.
