Managing RSO Side Effects: What to Expect and How to Cope

RSO can cause temporary side effects as your body adjusts. Here's what to watch for and how to manage them:

  • Drowsiness – Take RSO in the evening or reduce your dose if it interferes with daily activities.
  • Nausea – Take RSO with food or ginger tea to settle your stomach.
  • Dry mouth – Stay hydrated and chew sugar-free gum to stimulate saliva.
  • Dizziness – Sit or lie down until it passes, and avoid sudden movements.
  • Increased heart rate – This is usually temporary; practice deep breathing and rest.
  • Diarrhea – If persistent, reduce your dose and consult your doctor.

Most side effects diminish within a week as your body builds tolerance. If any symptom is severe or concerning, reach out to our support team—we're here 24/7.
