So far I have an experience similar to the OP, but I'm only on Day 2 of my Adderall
IR prescription of 20mg/day. I tried a few pills from a friend before that and also quit the Adderall XR prescription of 10mg/day that was causing me wild sleep problems and not being very effective at that dose. Before that I was on 10mg/day Ritalin
. The biggest problem with Adderall IR that I experience so far is that I seem to develop a tolerance to Adderall very quickly. Therefore, while the first day at a (higher) dosage might make me feel amazing, the next day is a vastly different experience. Also, I seem to get irritable easily when my Adderall isn't at a high enough dosage, which it rarely seems to be... although this could be due to sleep deprivation and/or stress I have been having at work... because I woke up feeling extremely stressed out about work the day I was to start my Adderall IR prescription (yesterday), and I couldn't de-stress until I hung out with my housemate late at night (she offered me a job + Adderall really makes my conversations more fun). And today I'm exhausted because I didn't sleep early enough last night... being exhausted on Adderall feels like shit.
Ritalin makes me feel physically uncomfortable and doesn't give me that feeling of immediate pleasure/joy that Adderall does, which is why I switched. But I didn't experience a wild difference between the first day and the next day on it, and it seemed to be sustainable over the long-term, or at least a few months, whereas I'm not sure Adderall will sustain me even a few days without needing a higher dosage. Adderall can really help me focus and accomplish things when I'm on a sufficient dosage AND when I'm not exhausted from the drug
keeping me up all the time in addition to draining my brain... but so far I'm not seeing that effect in the long-term. So maybe the biggest trade-off for me is between Adderall's immediate pleasure and Ritalin's long-term happiness. I felt unusually happy on Ritalin because I was getting shit done ALL THE TIME. Adderall has been a roller coaster between unusual levels of pleasure+focus and an almost nightmarish inability to ever be well-rested...
