i had been taking prednisone for a couple months for migraines before i told my doctor i didnt want to take it anymore. i had terrible mood swings, from depression to extreme joy. i would take it out on even my closest loved ones. my sexdrive also started to swing violently. i also had a swolen face and i bruised a lot easier. my blood was also a lot thinner. even when i cut myself shaving it would bleed for a half hour. i also became very tired and i couldnt concentrate. it helped my headaches though
