Sorry in advance for the length of this. I wake-up in the morning. As usual, I grab a joint I rolled the night before and smoke it while laying in bed. I reach over to grab my laptop and notice that I'm feeling kinda weird. (not high, just like hard to concentrate) I set the laptop down and sat on the side of my bed figuring it was just a head rush and it would go away. After sitting there for 30 seconds or so I had an INTENSE feeling that someone was coming to get me or something and I started to freak the fuck out. About nothing. For some reason I get up and start walking towards the kitchen... With every step I started to get tunnel vision and my body was getting really weak. As I am crossing under the doorway to the kitched my vision completely faded and I essentially collapsed. I was still concious the entire time but I felt like my body "unplugged" and I felt like I was dying. I don't know how long I was on the floor, but eventually I was slowly get up and lean over the kitchen counter. As I recovered, my ears were ringing and I had to remember to breathe. Slowly my sight came back and I felt fine 10 minutes later. I was a little slow mentally for a while after it happened but I seem to be fine now. This is the second time it has happened. The other time I was standing up after taking a bong rip and had the same symptoms above minus the panic attack. I during the time that this happened I was smoking around an ounce a month. The incidents are always related to weed somehow...? Any ideas whats going on? Kinda scary
