I was officially diagnosed with ADHD inattentive type two weeks ago, and I started taking 18 milligrams of Concerta every day. It would take 2 hours for me to feel an effect, and as soon as it did I felt like I was brought to life. Not only was I able to finish way before most of my classmates, but I was also able to zone them out when I had to complete a task, and I completed all my work in school instead of procrastinating in class and leaving the work off for home; I was more social because I finally felt like I had things to say, and when I would speak my thoughts would flow out in a coherent and linear way; I was able to talk about the books that I was reading and explain the concepts of the book quite easily; I was able to write my essay faster than usual because my mind wasn't wandering off all of the time, and I was able to be productive the entire day because my brain never got foggy like it usually would by the end of my third period.
However, there were a few side effects. My through felt dry, and I would feel pressure on the sides of my head which would make me feel a bit nauseous at times. All of these are tolerable because of all of the positive effects Concerta was having on my life. The reason I am considering stopping, though, is because I started to feel something weird in my heart: as if there was pressure on it that caused a subtle pain. I remembered reading that since this medication was a stimulant, It could have effects on your heart, so I contacted my doctor right away, and he told me to get off of it until my next appointment.
It has been three days since I have been off my medication, and the first two days were hard. I felt a sense of unexplainable sadness and brain fog which was more than the days before I ever took medication. I searched it up, and I saw that these could be withdrawal symptoms, but I am not sure if you could feel withdrawal symptoms after taking the medication for only 4 days.
In brief, because of the weird pain I felt in my heart and the potential withdrawal symptoms for long-term use, I am not sure what I should do. The benefits I saw from taking the medication were life-changing but I don't want to develop heart problems in the future. What advice could you give me?
