The length of time it takes to detox from Vyvanse will depend on several factors, including how long you have been taking the drug and your individual physiology. However, most people will feel withdrawal symptoms within a few days of stopping use. These symptoms can include fatigue, depression, anxiety, and irritability. Some people may also experience flu-like symptoms, such as fever and nausea. The intensity of these symptoms will typically peak after a few days and then gradually subside over the course of a week or two. However, some people may feel residual effects for months or even years after quitting. If you are struggling to detox from Vyvanse, it is vital to seek professional help. A qualified addiction specialist can develop a customized treatment plan to help reduce withdrawal symptoms and increase your chances of long-term success.
