Scoobygirlie,
Keep at it and it will get better. Keep hydrated with water and pedialite. If you are getting dizzy standing up, that is usually dehydration. The more you can not just sit around on the couch, the better. I know it is difficult as I went through it myself. I am on my 19th day clean now and getting much better each day. The energy will start coming back after you get through the sickly part. If you like to do anything that keeps your mind focused (crafts, puzzles, video games) then do it. There is a horrible urge to sit and wallow during this time and that is very unproductive. Hopefully your other half is supporting your recovery. You need that!
Keep seeking support here. There are many of us who have struggled through the same thing.
