I'm sure this will have been asked before but in my current brain fog I haven't the energy to search for it. Was on 50mg Sertraline until a month ago but still teary & not coping so gp doubled my dose to 100mg. Feel dreadful, constantly fatigued but unable to sleep, no improvement in mood & also constantly famished therefore eating all the wrong foods which makes me feel worse. Also having daily headaches. Anyone have any advice? I'm thinking I should ask to drop back to my original dose & see if I feel better??
