I have been taking adderall 30mg twice daily for 3 years, and the past six weeks i have been experiencing symptoms of dizziness,not being able to walk very well (rubbery legs) and in the past 2 weeks the symptoms has escilated to the rubbery legs my neck drawing into mid back really bad and my speech gets to where people can't understand what I say... An episode can last anywhere from 2 hours to 10 hours and it is random when it occurs.. And I can take hydrocodone 10mg and the episodes go away? Can adderall just now cause these episodes? And why does hydrocodone make them go away? I am a 39 year old male, the only thig that is wrong health wise is rapid de-cycling bi-polar, thats why I take the adderall, I have bottomless lows
