"i have had a lot of success with phentermine 37.5mg the first time was 3 years ago when i lost 30 pounds in 2 months.  i am 5&#039;3 and weighed 180 and after 2 months on phentermine i was at 150.  this time i am 45 years old and started out at 165 and after 1 month weigh 150 so i have lost 15 pounds which is the same rate i lost the weight before.  i do take the pill early in the morning around 6am if i do not i do experience insomnia.  i get full very fast after only taking a few bites of something i am done or i become nauseous.  phentermine has also caused me to have a dry mouth you just have to drink a lot of water which is good for you anyway.  all and all my experience has been very good.  it does really work.  just have a physical first"
