Hi, I recently took some antihistamine pills for my bad sun burn itch and I already have a fear of taking medication so I'm not suprised but soon the side effects kicked in (drowsiness) and I felt tired but I also felt really anxious and it made me feel very detached like I was dreaming. It's 1am for me and I can't sleep and I'm extremely anxious I caused brain damage :/ I took the right dose of two pills. Ugh I'm so afraid this is going to put in a DP spell. I'm not ready for this. Anyone experinced such a thing before?
