i had an inguinal hernia on the right side, had it repaired, took about four weeks before i really started to feel good, after that i took two more weeks, just because it happened on the job and they were paying my time off

. i don't know about a double, but i'd bet you'd be alright in the saddle after four weeks.
al.
forgot to mention, the pain meds are the worst! they make you constipated, and bearing down for a BM is NOT the most comfortable thing!! (you'll find out.)
