I'm thinking about taking phentermine. I'm 22 years old and currently 195 at 5'10". I want to be 150. Earlier this year i lost 25 pounds doing diet and exercise. I gained it all back

I haven't had much motivation to lose weight lately, even though i detest the way i look. I thought that taking phentermine would help me kick start a new me. But i have some questions before i spend a lot of money on this (i'm a college student, so extra money is hard to come by). First off, does it work? I see a lot of sucess stories on here, but have some people had bad experiences? Next, does it have any side effects? I'm really concerned about this one (although i've never encountered side effects from any medicine). I don't want to have health problems as a result of taking this drug. Any and all insight would be wonder
Thanks!
