gonna share my experience since it was a lil different than any other time I have experienced this... I pushed the needle into my quad and noticed that i was in a vein most likely. I pulled out and went to another spot and aspirated. Everything was ok and I injected the gear.. Then after maybe 2 minutes I start to feel the need to cough and feeling a little light headed.. Well at this point the symptoms were very mild commpared to previous cases and I was thinking that I just barely nicked a vein.. The weird thing is that eventhough the initial symptoms were weak I had terrible night sweats and today Im barely functional... Just feeling a lil bad.. Im not getting sick or anything, feel just weak after this thing.. Now im almost 100% normal but even still I feel like I need to cough constantly. What wonders me is that y the initial things were so weak but now I feel even worse after 16 hours than after my major incident with nicking a vein (then I prettty much passed ouut for some hours in the bathroom and was coughing for hours). strange. all is good now, not trying to ask a question, just think its strange.. ofcourse if some1 has an explanation..
