I upped my citalopram a few days back from 30mg to 40mg and the first 3days i had nausea then since yesterday i have been feeling really anxious / sickly scared feeling with this knot feeling just below ribs, slept all day then wide awake all night i just cant seem to relax..

i remember when i first started the cit that i felt a lot worse but cant remember all the side effects every time they have been upped i just thought that i have been on them a while now that upping them to 40mg i wouldn't get any more side effects or do you get them every time they get upped ??
so is this normal the way am feeling ?
