I went to the ER almost three days ago for nausea and vomiting and was put on an IV of reglan. I began feeling agitated and the doctor told me that this was normal. I wanted to get out of there but kept my calm and managed to get home afterwards. I'm still suffering from the anxiety and depression and I can't sleep! can anyone tell me if and when these symptoms wear off? is my brain permanently damaged? I'm terrified and worried thinking what I am going to do now if I have to quit my job, how I am going to take care of myself. thank you for reading and if you have any advice for me
