i weigh 170 pounds and im 6 foot 2 i took 288mg of concerta over a 4 hour period while drinking about 6 shots of 80 proof alcohoo (dumb i know) i started taking them at around 6 or 7 and took the last one at 1 a.m. its now 8a.m. and im still speeding really hard. i read that 240-300 is at risk for overdose so im kinda panicked. my heart rate is normal which is weird and kind of worries me., i was prescribed methylphenidate for 8 years so i have a higher tolerance i guess? (never abused it till last night) i guess what im asking is, am i at risk of overdosing, or would something have already happened by now? (7 hours after the last one i took) sorry for the grammatical errors, just trying to figure out if i need to seek medical attention or if i sleep it off ill be fine.
