As soon as you stop using CPAP, your breathing during the night will get worse. This means your daytime symptoms will come back. Think back to how things were before you started CPAP. There is a risk of going back to feeling this way. You may suffer from morning headaches and feel tired and moody during the day. Everyone is different and the time is takes for onset of these symptoms will vary, but it is possible that these may come back after the first night with no CPAP. Feeling tired during the day is a potential problem. This will raise your risk of road and other accidents if you are driving on your holiday or travels. If you feel tired, do not drive as you and others will be at risk.
