My doctor originally perscribed me Adderall XR 20mg, however I don't have health insurance, and the prescription was $189 for thirty capsules, so I switched to the immediate release 20mg. I took it this morning and had a huge crash this afternoon about 7 hours later. I work 9-10 hour days and go to school full time, so I can't afford a crash. Could I take half the dose in the morning and half I'm the afternoon? Would it work similar to the XR?
The difference between XRs and IRs is that a 20 mg XR releases 10-15 mg at first then (what it says it does but after experience I must disagree with) 5-6 hours later releases the remaining 10-5 mg. A 20 mg IR releases all 20 mg at once, and since you went from 20 mg XRs to 20 mg IRs you kind of doubled your original dosage, which would account for a hard crash 7 hours later, IRs usually last, after you get used to it about 4 hours. Taking half an IR in the morning then the other half later is totally ok, I actually know a lot of people who do this, and I'm more than positive your doctor won't disagree or argue with you doing this. To avoid a hard crash I would stop taking the 20 mg IRs all at once and split them up, then do what you should always do and stay hydrated and make sure to keep some food or some sort of sustenance in your belly. I've pretty much avoided all crashes by sticking to drinking a lot of water and always making sure I either eat or drink a health shake between my two doses throughout the day. Just remember to tell your doctor that you're doing this, because Adderall is such an easily abused drug doctors tend to like to know what their patients are doing if taking differently than prescribed, even if it is a totally ok idea. One more thing, by splitting a 20 mg IR in two and taking the two halves at your choosing, you're pretty much making the IR into what I would call a true XR. Damn, one more thing, no you can't split XRs in half. The different colored beads break down at different times so splitting one is next to impossible. Hope this helps out, if you have anymore questions or if I forgot to answer something feel free to ask. Best of luck.
