I was prescribed promethazine on 12-10-13 & stopped using it on 12-15 cuz I realized it was causing delirium, shakiness, nausea, headaches... I'm still experiencing nausea, headaches, shakiness, lightheadedness, & delirium. Will these symptoms go away on their own? How long will it take? I have no health ins & can't afford 2 go 2 Dr. but can't afford 2 keep missing work. What 2 do? Please help! Thx!
