how do I control/ help brain shivers/zaps?

If you read my last question about me dealing withdrawl I haven't been able to get to a doctor. If you didn't I've been taking paxil(20 mg) for a long time and yeah I have no pills left at all. Now, I've been trying to cope with the terrible feeling of brain shivers/ zaps or whatever you call them and I wanted to know is there a vitamin, drink, exercise, something to control, help ease the feeling of the shivers before I can get to the doctor? It would help me alot. I can't make an appointment till monday and I wasn't able to work today because my manager said I looked so bad she said I shouldn't work. As you can understand I cannot miss any more days. If there is anything at all I could do I'd really appreciate it. Thank you!
