Digitization. When an analog waveform is converted to a digital file, the analog information must first be translated into bits. This is done through sampling, a process performed by a computer's Analog to Digital Converter (ADC) hardware.
For example, the drowsiness effect of trazodone can be helpful for people who have insomnia. Trazodone is especially useful as a sleep aid in people with depression, since it is effective for both insomnia and depression. Conversely, some antidepressants are likely to cause insomnia, even when taken in the morning. Trazodone can be used to treat insomnia caused by other antidepressant medications.
Because trazodone may not work well to treat insomnia after a few weeks, check in with your doctor periodically to discuss how or if it's still working. If you have trouble getting to sleep, take it several hours before you go to bed; if you have trouble staying asleep, take it within 30 minutes before bedtime.
