You are taking underdose of nexito. If you are trying to stop the medicine you will experience some of its withdrawal symptoms such as sleeplessness, anxiety, feeling of something not good.
These symptoms might bother you for 7 to 10 days. But if you don't focus on them they will gradually subside. Do not get apprehensive that you are going to stop medicine.
Next Steps
If you are unable to stop it you can start taking 5 mg of nexito.
