Just go to your regular doctor. I've been 3 different times, I basically don't have insurance, so it's $80 for the visit, they will give you some kind of valiumesque medicine to get you through the next couple days that will help with your seizures and ease the detox, if you need something to sleep they will usually give you something for that too. The meds usually cost me about $150. It's cost me a couple hundred dollars each time I've gone to the doc to detox but it's been well worth it, you can sleep and it makes it much easier. The last time I went I also got a prescription for antabuse. You may want to consult your doctor and consider it. I think it's a life saver for me.
Also, going foward, you have to get it through your head, (we all do) that we will NEVER be able to control the 2nd-20th drink, the ONLY drink you can control as an alcoholic is the first one.
Hoping you get better soon I know detox sucks.
