im on 36 mg concerta....but it wasnt doing much for me except making me LESS motivated and a headache. like a ******* i doubled my dose today and that brought me to 72 mg i believe. my chest hurts. . my heart rate is 126. i know im not going to die. but just how bad is the damage of a sustained releaxed heart rate of 126 for hours? im pretty sure its been like this all day, but i just checked now. im 19 years old and weigh 170 lbs. please respond soon. also what is the dangers of mixing concerta (extended release ritalin) with alcohol. the only reason i want to do that is to lower my heart rate sense it is a depressent. thanks.

update: im fine now, just not used to tension in my chest. i read a thread on here that they are making a 72 mg concerta. how anyone can take this everyday is beyond me. ill stick to 36 thank u much.

That is most certainly NOT a healthy sustainable heartrate. Glad you're doing better now.
