Losartan
"This medicine was horrible for me.  At first, I was on one by a manufacturer that had it in little green oval pills.  I did have anxiety and never wanted my sister to leave me after I took the pill.  However, I felt fairly normal (although, not completely).   The pharmacy switched manufactuers and they were then little white pills that looked almost like aspirin.  The anxiety got terrible then.  I had the strong feeling of buzzing from inside my head to all the way around it.  I wanted my sister to stay with me ALL THE TIME.   I didn't even want her to leave for ONE MINUTE.   I was lucky if I could handle going to the bathroom alone.   I HATED being alone.   I don't like being alone as it is, but I can usually handle being alone for an hour"
