Thats how I feel exactly I felt an extreme urge to go outside and get fresh air and kind of unconsciously walked out. Then just sat on the curb with a throbbing head buzz and no visuals as well as burning lungs.the more extreme feelings are the worst,nothing makes sense to u AT ALL,sometimes u hallucinate,buy only on the extreme feelings,and it only last like 5-10 minutes ,not worth spendin that much money on,get a bong and a regular lighter to have the moderate feelings(laugh ur ass off)and a jet lighter to get extreme,and don't get like 60x extracts and shit,thats some exreme shit
