"after 10 years of chronic abdominal pain, a bunch of tests, multiple doctors telling me to take ompeprazole with no relief i am now 90% pain free. i started taking endep 1 week ago and have increased  to 20 mg. it makes me a little sleepy but i take it 2 hrs before bed anyway. my new doc narrowed it down to overactive nerves and she nailed it. i&#039;m now getting better quality of life and am happy that i have found this med. for me it&#039;s really worked well."
