I don't think any of us can answer that. If in doubt go to the ER, they can evaluate the situation medically.
Each of our bodies are different. Even if we told you our own intakes, habits, etc I think it depends on a lot if factors that only a doctor could address. Do not use that as an excuse. I did for over a year "oh, it's not safe to stop at this point". I did eventually quit cold turkey, but I had seen a number of different doctors recently for a number of different checks. Get to a doctor, you need to quit. Good luck!
