I had my ET (we are only doing one at a time) yesterday... and I did not sleep all night... was a little uncomfortable. Today, I am very crampy - like down my legs (especially my thighs)... I hope this ET works... Out of the 17 removed I could only freeze one other one :-(

Re: How'd you feel after ET?
Complete Edit: I thought I was on TTGP ::bangs head into wall::
No advice but I hope you feel better!
