I took a 2 hour rest in bed to ease my backache when I had this sudden extreme agitation came on. Just felt like punching the wall. Tried fist clenching & teeth biting to no avail. It was very scary. This was gradually relieved after I took some food. Anyone had this experience before? I'm on clonozepam, melatonin spray (with gaba), lamictal, L-glutamine, magnesium & slow K. Could this be a consequence of an untreated gastroparesis-like symptom for the past 6 months? Specialist gastro docs gave up on me after I could not tolerate gaviscon, domperidone (supposed to treat gastroparesis) and nizatidine. Could this be due to brain being starved of oxygen & nutrients? Food & water sitting in stomach throughout day & night.
