I find it really hard to wake up in the morning, until I've had a cup of coffee and the vyvanse has kicked in. I'm messing with the dose, trying to get it right, even dumping out some of the 40 mg. capsule. I can't skip a day, can't stand feeling brainless. Even with vyvanse between 30 to 40 mg. I still struggle with motivation and fogginess. But, too much vyvanse and I'm jittery. Adderall and dextroamphetamine was worse for jitters though. I also deal with depression and anxiety all the time as well. And insomnia started this year. I need xanax for that.
