I have been on adderall for a year now. For the first 3 months or so I took 2 pills a day, morning and afternoon. But that mid- day crash is the worst!! It’s liked you just ate 5 doughnuts and a slirpy. My psych. put me on the extended release (xr) and they worked amazingly. 5 mg is a very small amount. People develop a tolerance to it so you could probably up it and do the XR. Just ask your psych.
