Anybody tried this place? http://www.aboutyouhairremoval.com - full day (or two) of electrolysis under sedation... Sounds similar to E3000 in Dallas, no?

Yes it does sound like E3000 in Texas. The differences I noted were the "twilight sedation" and higher costs.

It's similar, it's where I go.  I believe E3000 only does the lidocaine injections.  The chicago place gives you conscious sedation and the injections together.

Having it all done at once like this increases the chances of incurring skin damage.

If you're in Chicago, I can highly recommend Cassie McCabe for traditional electrolysis.
