I had the same experience this break. When off my Adderall for about 8 days, went back on and felt sooo much better. Expect for the first 2 day where I was a bit tired I had no real physical symptoms being off the med. However, while off I had trouble sleeping and I just could not stick with anything long enough to finish it. I went back on last week because it was crunch time, I had a few follow up med appointments and T. The last time I tried to do Twhile being off the med I really had trouble organizing my thoughts. I didn't want that after being on break.

Then I was out of town taking a few workshops this week and FORGOT my meds. Not good, sitting in boring lectures without medication, I was again bouncing off the wall. I'll be back into my regular med routine tomorrow and glad for it.
