Phentermine!!

exm ♥️
Anyone have experiences with this?? Went into my doctor and inquired about weight management and she immediately wrote me a prescription for 37.5mg of Phentermine. I thought it was kinda strange that her first option was a diet pill but 🤷🏻‍♀️
Anyway. I didn't have my first meal of the day until about 2:00 and I took my first phentermine tablet with it. About an hour or so later I'm laying in bed watching a movie with my boyfriend and I get kind of dizzy and extremely tired. I drank a small bottle of Gatorade and then my boyfriend and I went to eat at a dining hall and it helped me feel a bit better, though I still felt a little off. I'm assuming it's because I haven't had 3 full meals of the day quite yet? Idk I'm kinda hesitant to continue taking it, but I've already spent $40 on it so I don't want my money to go to waste. Just wondering if any of you have experiences with this prescription. Thanks!
