Is It Safe To Take Dextroamphetamine Or Adderall For ADHD?

ADHD medication question. I have previously taken Vyvanse and didn t like it. I was on Adderall up until yesterday and today I tried dextroamphetamine tablets. It reminded me a lot of Vyvanse and came with a lot of the same problems. How likely is it that my experiences today are due to it being the first day I tried it? How long should Continue to try it before going back to Adderall, which I liked and was doing well on. I m also in a time frame where I have a job interview in 2-3 weeks and would like to have this figured out well before then.
