I realize I got lucky with my GP here in the States, but he did talk about things with me when I went on phentermine to help with weight loss. All the withdrawal symptoms, why I must stop taking it every three months, etc. He even went over every result in my blood work and thoroughly explained each. I think I was in that appointment for two hours, and it was amazing. I wish more physicians were like him, though I also realize they're pressed for time a lot of times and such, which doesn't help.
