i just joined the site.. so this is kind of a late reply i know. i just got my results for a blood test and it seems that i have hyperthyroidism. haven´t take them to the doctor though. IT IS dangerous to roll if you have hyperthyroid. your heart is already beating faster than normal and if you add amphetamines it makes the matters worse. i´ve been doing online research and haven´t found any case that says that someone with thyroid problems died of heart failure, but there has been people that certainly died from hyperthermia. thyroid regulates body temperature, if you have hypo you feel cold if you have hyper you feel hot. iknow from expderience that lsd makes me sweat a lot and i feel like i have a fever.. my boyfriend doesnt get that same effect so im wondering if its really my disease. huh...
