I ve just started taking sertraline, I m in my 2nd day of it, already I am getting pains in the back of my neck which in tern turn into headaches, I m also feeling sick and dizzy, also I m finding that the sertraline 50mg is making me want to sleep with In an hour or taking them, and within 15-20min of taking them I feel as if I am feeling cold, like I walked out in the snow with summer clothes. Day one: Sleepy within 1hour of taking sertraline, a feeling of heartburn after taking sertraline, later turning into passing of wind that feels like it burns, both in burps and flatulence while the heartburn continued. felling very dizzy, ears started to ring, and feeling as if I was cold within 30min of taking sertraline Day 2 (today): Had problems sleeping at night waking up every hour or so. ringing in my ears, sticky-runny stools, dizzy spells where I had to lay down until it passed, neck pain at the back of the neck to the base of the skull so intense is triggered a dizzy spell. Feeling of being cold within 30mins of taking sertraline, Feeling sleepy within an hour of taking sertraline, Dry mouth, headache and heartburn. Is this normal or should I be already talking to my GP about coming off. If I m honest I would rather fight my panic attacks then be feeling so unwell like this, this is more scary then having trouble breathing alone.
