If you feel the least little bit 'off' please go to University Medical Center (formerly Thomason Hospital) ER IMMEDIATELY. They will take care of you and get you into detox.
Yes, I am in Las Cruces, and have worked with 'wet ones' many times in El Paso. We always used Thomason. Nothing has changed but the name, now that UTEP has a medical school, Thomason has become University Medical Center.
There is no reason to try detoxing on your own, that is way too dangerous.
Once the worst of the 'toxins' are out of your system will be time enough to start researching recovery programs and decide which one you would like to try.
