Forced off pristiq cold turkey!

A week ago, I emailed my doctor asking if I needed to make an apt to get a new prescription for my pristiq (100mg daily) or whether he could just get me the prescription. He said he could just get me the prescription and that he would have it ready for me. Well, he didn't. He kept postponing it and now I cant reach him. I am out of my meds completely and on day 3 of no pristiq. I have no mental symptoms, only physical ones: the brain zaps, nausea, dizziness, disorientation, always cold and always thirsty, etc. Its really scary and I dont know what to expect. I cant function normally and would like to know when it will start to ease up and what I can take to ease the symptoms.

Last night it was so bad that my husband took me to the ER. I could not be seen. The nurse that screens patients and determines priority was so EXTREMELY rude and mean. He would not even let me explain whats going on before going off on me about how trivial this is and how my withdrawals were nothing compared to the kid in the lobby with the minor cut on his head (that was already healing). He was so rude that I had to leave. It upset me really bad.

I tried calling my doctors office this morning and they can't make me an apt to see him anytime in the near future.

I wasnt intending on getting of these meds (let alone cold turkey!), but now that I'm going through withdrawals, it seems like something i dont want to be on. This was forced on me, but I think getting off of it is for the best. I would just like to know how long does it usually take to at least get to the point where I can at least try to function normally. Also, are there any natural remedies? (note: many medications do not affect me. Benadryl, headache meds, cold meds, etc dont do anything for me.
