Clonazepam discontinuation symptoms were mostly mild and included mainly: anxiety, shaking/trembling/tremor, nausea/vomiting, insomnia/nightmares, excessive sweating, tachycardia/palpitations, headache, weakness, and muscle aches. Mainly depends on how long you have been taking and how much dose. In your case it is very less dose (0.5mg) and it's short duration. Clonazepam can be successfully discontinued without any major withdrawal symptoms if the dose is reduced gradually. Clonazepam is by reducing the total daily dose by 0.125 mg (1/8 mg) on a weekly basis. So if you were taking 0.5mg of clonazepam per day, it would take you approximately 4 weeks (1month) to fully withdraw to 0 mg. Continue rest of your medicine.
