I am recently prescribed to adderall and took two 20mg xr this morning and they appeared to have worn off, and i really needed to get a huge project done so i took another 2. I have been exhibiting almost all signs of an overdose with the exception of a heart attack or stroke. Most of the symptoms seem to have peaked. I only have a headache and a mild fever now. But before i had numbness on both arms/legs, fingers/toes; nausea/vomiting, shortness of breath, cold sweats. I should be fine soon but is it ok for me to sleep? Im exhausted from the ordeal
