Alright, excuse me if these have been asked, I'm new and tried searching.

Two weeks ago I started adderall IR barr type. I have to say, starting out on 15mg a day was terrible, upped it to 22.5, terrible, upped it to 30mg, terrible. Today, I went to 45mg and feel amazing. I can't wait until my doctor tells me to go 60mg+ and see what that does. Now, my question is, I have a class that starts at 4PM and another at 5PM and I would like the duration to last through those times. I took 45mg this morning at 10:20am. My question is, how do I keep the feeling of what I have on 45mg through my 4-5 classes? I was told to just take 1 15mg tablet and that would add on to the duration, but when I would do that in the past, it would make me feel horrible. So basically, what do I have to take/do in order to keep this going through my 4-5pm classes?

Great questions. Don't know the answer, but someone here will.

If it is IR, then it should wear off after 4 to 5 hours (50% of it is still in your system after 13 hours, so it's just that after 4 hours the effectiveness in the brain isn't as high).

Adderall IR is fairly similar to Dex, and with Dex I just take dose 2 in the same quantity 4 hours after dose 1.

Titrate again. Try 30mg then 40mg and see what happens.

P.S.: Just because 45mg works, don't assume 60mg does.

Also you have to work it properly so you're not taking a tablet at like 2 or 3pm (it'll probably keep you awake at night). Try 9am then 1pm.

Have you consulted your doctor?

Yeah, I have.

She wants me on AT LEAST 60mg because of my size. That's fine, I'll be more than happy to go up mainly because it feels like the more I have, the better I feel off. Especially if I just took 15mg, which I did yesterday at 6pm, it made me want to sleep instead of study, and then when it wore of it made me stay awake till 7:30AM instead of sleep. But I feel as if I won't have that if I keep going up.

I took my 45mg at about, err, 10:10-10:20 AM. I only need to take more on Tues/Thurs, so should I take them at around 2-3?

I was going to start a new thread, but this is exactly the kind of info I was looking for.
I was taking Adderall IR almost a year ago, and my doctor pretty much told me to try adjusting my times and dosages myself (while keeping him updated). I got frustrated and stopped taking it, but now I'm desperate to give it another chance.
I was taking 10mg, twice a day, but I found that the first dose (6 or 7am) wasn't as effective as I had hoped, and the second, no matter what time I took it, kept me up into the wee hours.
I'm making an appointment for the coming week, but I'm trying to write down points to raise and questions to ask. Would XR be a reasonable option, or might that just make things worse? Might two different dosages for the two different times help? I just can't take the late nights and the attempts to "jumpstart" in the morning!
