It's common to experience headaches after quitting drugs due to withdrawal effects. To help manage this, ensure you stay well-hydrated, get enough rest, and avoid caffeine or alcohol, which can worsen headaches.

• If you were using medications like Varnitrip-1 (varenicline) to quit nicotine, some headaches may be side effects of the medicine and usually improve over time.
• Over-the-counter pain relievers like paracetamol can help, but avoid self-medicating without consulting your doctor.
• If headaches are severe, persistent, or accompanied by other symptoms like dizziness, confusion, or vision changes, seek medical attention promptly.

Please consult a specialist doctor, such as an addiction medicine expert or neurologist, to guide you safely through withdrawal and manage symptoms effectively.
