You might be being a little too rough during lysis, or maybe 
lysing too long. Try gentle inversion, just enough to mix. Also, 
when you remove your aqueous layer after extraction, leave behind 
a little something for the fairies. If you must be greedy, just 
extract the organic fraction again. I hope this helps.
