"been on phentermine 1 month, today was 1 month appointment with my doctor. i have to go in every month and show any weight loss in order to get next month prescription. i lost 23 pounds in 1 month and am thrilled. wasn&#039;t able to exercise due to pneumonia. but plan to in month 2. side affects were little dry mouth that water cures, and if i don&#039;t take phentermine in the morning but later i have trouble getting to sleep. the medication after first couple of days really curbs appetite and i have to really make myself eat, and because i&#039;m not hungry i am able to take my time and make good choices on what i eat!!! also blood pressure is way down. looking forward to month 2, and being able to feel healthier with more weight off!!"
