I am barely writing this, severe headache and nausea. Also vomited. About a week ago I stopped taking sertraline 50mg cold turkey. I was relatively fine the past few days, mild headache and some brain zaps. Two days ago i started taking 100 mg 5htp. This morning I woke up with a headache but no nausea then i had breakfast and took 5htp. After a few minutes it got very bad and i dont know what happened or what to do...
