Brief Answer:
Hello. You need to wait at least 24 hours before resuming at 20 mg

Detailed Answer:
Hello. I don't know exactly what the bad side effects were, but you need to wait at least 24 hours before resuming at the 20 mg dosage. At that point the previous dose will be out of your system. You should also discuss this with your doctor.
