ADHD
"I took 15 mg instant release Ritalin for ADHD, to combat daytime sleepiness, and focus on med school studies. I have mixed feelings about this medication. It improved my focus a lot, but it also had some negative effects. I was very nauseous after taking the pill and would sometimes gag. Nausea was absent on days I didn&#039;t take it. I had no appetite so I wasn&#039;t eating enough, which isn&#039;t ideal because I am already thin and not looking to lose weight. I would try to eat before taking the pill but I did notice either a decreased efficacy of the drug. It also increased my heart rate to about 120 beats per min (I am normally about 75). This did help me feel motivated and get work done, I just wish I didn&#039;t experience these side effects."
