"when i first started taking it, i thought it was great. i took the 20&#039;s twice a day with 10 mg hydro for breakthrough. i have been on it a year and my doctor said i needed the 30 mg but he is closing his practice and won&#039;t change any prescriptions before he goes. he said i needed the 30s about a year ago but then wouldn&#039;t make the change. i took myself off of them. they only gave me about 3 hours of relief after taking 2 hours to be effective. so now i am looking for a new doctor who will just give me 30mg of hydrocodone a day. that&#039;s all i need."
