Sorry to hear you are not feeling well. One of the best things you can do for yourself during this time is drink plenty of water.
I just went off Mirpaex and didn't have any withdrawls. I also am missing 100mg/day of my Lamictal b/c an error occured with my drug plan and so I can't get my meds for 5 to 10 days until they have it fixed. Oh I can't even talk about it, it still upsets me so much....
Anyway, try to take it easy, get rest, drink water and I hope you are feeling better soon. I know you've had such frustration with all of this.
