 [ Symptoms ] i od meth 3 days ago but still feel off if an overdose kills someone does it only occur immediately  i am concerned because i am not sure if how i feel is withdrawal or something potentially fatal like maybe slow kidney failure is that possible days later i am periodically a little shaking throat feels a little tight my heartbeat seems a tad off and a little tight temperature is 96 5 my comprehension is somewhat distracted e g when reading textbooks [ Disease ] i am sorry to hear you are going through this and hope you get treatment so you get off the meth for good what a wonderful holiday gift that would be to yourself and your loved ones a methamphetamine overdose can cause serious medical problems that linger for a long time because methamphetamine overdose can cause abnormally high blood pressure it is possible for a person to suffer a major or minor stroke kidney problems and heart dysrythmias the effects of any of these things can linger for some time and i barely scratched the surface in terms of the damage a methamphetamine overdose can do to a body  if you did not receive medical treatment for your meth overdose i strongly suggest you seek medical attention now a physical exam can help identify if your overdose caused any permanent medical problems i wish you peace
