ADHD. On Ritalin And Adderall. Should I Take Celexa Too?

Hi yes i have been diagnosed with adhd since i was 8 . First Ritalin then later in my older yrs generic adderall 30mg tabs 2 bid and then i was switched to 20mg tabs tid . They have always helped me concentrate better, focus as much as i possibly can, and they keep my mind from racing fast where i cant keep up with all 100 things i start and cant complete. When i was younger they also contolled my actting out . Recently i have stopped gojng to my psychiatrist because im trying to quit the suboxone that ive been on for 2 yrs , i think he isnt helping me and the doctor who was left the clinic. I am only prescribed celexa 20mg . I have no problems with weight loss or lack of sleep . I dont have ins right now so i payed for scrips and cant afford another doctor especially because my 7yr old is also in need of meds to and hers are pricey. Can u help me ?
