I used to have bad acne as well, but a different approach worked for me. I went on Tetracycline to start, then Septra, and my doctor wanted to put me on Acutane. But after reading about the side effects such as hair loss and the heavy duty stuff that your body has to process, I really didn't want to take it. And I realize it's worked for many people, and for really bad cases, it may be your only option, but for me, the ends didn't justify the means - it just seemed to toxic and intense - I was concerned with long-term effects and the side effects you don't know about, because they always exist.
Instead, I put up with it until about 4 years ago. That's when I started changing my lifestyle. I cut out pop, chips, pizza, fast food, all that garbage. My sugar intake went way down, and I started eating healthy and going to the gym - I had never gone before in my entire life. Whether it was due to me purging my body of all those toxins (cutting back on sugar, greasy food, dropping 30+ pounds, etc.), or due to my immune system finally getting the proper fuel that it needed (healthy food) to work properly and fight infection better, I don't know, but my acne fully cleared up naturally, with no medication at all. I am now in the best shape of my life and healthier than I have ever been - I no longer need any medication for anything, all my ailments have disappeared, and I never get sick anymore. It's wonderful!
I'm not saying this would work for everyone, as I'm sure there are some people out there who have worse acne than I did, but I wanted to share my story regardless. It is another experience which adds to my ever-growing list of why I dislike many (not all) doctor's mentalities and the health care system in general. All the doctors I have been to have always been so quick to prescribe drugs for me - for everything. I have found time and time again that they basically have tunnel vision, are quick to write me a prescription for anything, and never think outside the box. It was the same with my asthma - I was on medication for it for years and years. Then, once I started changing my lifestyle and actually becoming healthy, it went away - I haven't needed an inhaler for the past 4 years. So for me, 15 years of drugs could not accomplish what 3 years of no medication and healthy living did.
So that's basically my rant - doctors seem to look at drugs as the only possible solution to ailments, and the "health care system" in general is more of a "disease care system" - they only treat you after you have an ailment, and just push drugs to mask or postpone symptoms without being preventative and proactive in helping you not become sick in the first place. I realize acne is a different matter of course, but still, just had to get that out there...
Anyway, that's my story for what it's worth.
