Only had one serious attack before but it was one of the worst feelings I've ever came across..... it happened at a music festival during summer. A friend bought like a whole cooler full of gourmet ganja food and he kept handing me bites to sample. Like truffles, kief frosting, ice cream really tasty shit and so needless to say I had way too much. This was a couple days into the festivities and yelling, all the dust in the air, and ingesting copious amounts of drugs had me losing my voice and it was swelling out my throat bigtime. I believe the combination of the two set it off felt horrible and I couldn't speak a word, barely whispers and my chest was super tight. I had my potna walk with me to a medical tent and they said don't worry just drink gaterade while the whole time I felt like I was gonna die. Ended up hiding out in this girls tent cause I was over trying to explain to everyone coming up to me why I looked so bad and couldn't talk. Felt high strung from the anxiety but ready to nod out from all the dank food like an energy battle .
