Cocaine make you feel full of energy and wide awake. These good feelings stop after about 15 minutes, and you can start feeling uncomfortable, sad and wanting more. You can also become restless and think people are out to get you.
When you keep using cocaine, the bad feeling will often get worse and can include seeing things that aren’t there, heart problems and no longer being able to have sex.
When you stop using, after a day or so you can get withdrawal symptoms. You may feel angry, sad, very hungry, very tired, not able to sleep well, and wanting to use cocaine again. These feelings can last up to 10 weeks.
