That happens to me, and I'm pretty sure it has to do with my meds. I get really jittery and hyper and I feel euphoric for a few hours, like nothing can touch me and absolutely nothing is wrong. My whole body can get kind of twitchy and restless, which is especially bad if I'm trying to get to sleep. So you're not alone in those symptoms. Have you spoken to your doctor about this? Maybe your meds need adjusting?
