You have to go to a doctor. You have to go. This is not a predictable thing. Withdrawals are very, very serious. They should always be under medical care, always. No exceptions. None.
Please do not take this lightly, go to an ER if you have to, whatever it takes. Please. Please listen to this. Do not tell yourself that if you feel ok now, you will feel ok later, or that you can weather it. Just seek medical care and make this your absolute number one priority right now so that later we can hear of your sobriety.
You asked, and this is my answer and I have experience with withdrawals.
