amberskye, you're taking this personally and in the wrong way. There's nothing wrong with sharing your personal experience on the matter, so long as it doesn't encourage the OP to engage in otherwise risky behavior that only a minority of patients can handle. Like an old statistic I'm remembering now, cigarette smokers have like a 25-75% chance of getting lung cancer, I believe the figure is that only 1 in 4 smokers don't get cancer. So those 25% who didn't get cancer, when they share their experiences with smoking, often mislead others by giving them a false sense of security.
I know this is a rather extreme example, and I know that especially in the past, and again lately in the present (an issue we are currently working on addressing) people recommend using drugs inappropriately. There are situations where it's fine to share personal experiences with medications, but it's also important for others to realize that there are certain personal experiences that may have had a certain effect on you, but it is not at all guaranteed that this effect is universal, or that others will react in the same or even remotely similar way.
Everyone's body chemistry is unique, which is why it's important to consult professionals who can do things like do bloodwork and give you patient-specific lifestyle change advice, and of course, medication if it's necessary. However, self medicating using amphetamines for weightloss turned out to be a disaster for the people I knew who attempted it. Amphetamines themselves can induce a plethora of their own health conditions, and they put extra stress on your heart, just like with obesity, so unless you're open to tackling your weight from multiple angles and perspectives, like by exercising, dieting, possibly medicating as per the doctors recommendation, etc, you won't lose much weight, at least not in a healthy way. It can be dangerous to rely on amphetamines alone as monotherapy for weight loss.
It's very important to treat the underlying conditions that lead to the unwanted weight gain in the first place, to treat and prevent this in the future.
