"i have ran the gauntlet of add meds, starting with concerta then tried vyvance which worked well in the beginning,  then my dr switched to adderall xr,  then to i r, which works best for me i take 20mg twice a day definitely helps with non stop thinking,  racing thoughts,  and just simply getting motivated.  i have been on the ir for about a year and the highs are finally outweighing the lows. 39 years old and can see light at the end of the tunnel."
