I take sertraline (zoloft, 200ml a day all at once) for anxiety. Recently I ve had an ongoing headache and taking Excedrin extras strength, and taken quite a bit, maybe 16 tablets in 2 days, also been using Orejel for a mouth sore. I also drink a lot of soda, and I took 3 more tables of Excedrin and it made me vomit almost immediately after taking it. Even though I had eaten about 8 hours ago, I vomited only what I took to take the pills, soda. It gave me a pretty big anxiety attack as I don t get sick much. Before today, the last time I had gotten sick and vomited was like 12 years ago. Should I be concerned of overdose? Age: 24 Height: 5 6 (maybe 5 7 ) Weight: 138 lbs I got Lyme disease when I was 13, a pretty advanced stage of it, also ammonia when I was about 8. Other than that, nothing severe.
