Hi - What do people use when their doctor will no longer prescribe Phentermine? I lost 70 ilbs in 9 months last year, want to lose 20 more to reach goal. What over the counter is most like Phen? I hate to stop losing now but doctor is conservative about total time on Phen. Looking for product for appetite suppression and high energy feeling. Was taking 37.5 mg of Phen 1 x day. Thanks for any info!
