Hello, Your symptoms are due to caffeine excess and ADHD drug. Your symptoms will persist till the time these remain in blood in high dose. With time as the level will decrease the symptoms will subside. Take any over the counter anti-acidity product or prescription drug as tablet Pantoprazole two times a day. Just relax, symptoms will pass out after some hours and do not take any additional drug. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Varinder Joshi
