Concerta
"Was on Concerta xl for 7 days and had to come off it due to the unbearable side effects of the drug. I  was diagnosed with ADHD (inattentive sub type) generalised anxiety and depression. This drug made me feel very nauseous, gave me a headache, made me shake, gave me twitches throughout my body, messed my brain up in terms of cognition etc, made me very aware of my heartbeat, made me extremely anxious to the point of not being able to leave my room or communicate with anyone and just generally messed me up. At one point i was doing some stretching on a yoga mat to try and calm myself down and i felt so confused that i didn't know what to do with my legs. This drug wasn't for me and caused an unpleasant experience."
