I know what you mean. It seems like everything effects everything else. I have been on the spiro for 6 months...now at 50 mg / day... and the yasmin for about 9 weeks (all active pills) and still I am breaking out. I am at the point where I am really ready to give up and just go back to taking the accutane 5 days per week. This is the only way I stay remotely clear. I just want to so bad eliminate the accutane from my life. I've done fine on it, but I really was hoping to be able to control this with the other two meds. I am frustrated and irritated at the same time. I started to use the tazorac before I wash my face for 2 - 4 minutes as directed by my derm. It's only been 1 day, so we will see, but I am no about to put it on my entire face!!! I will try to use it on the same side for about a week to see if I break out bad. I'll probably have red peeling and burnt looking skin on one side and the same onld breakouts on the other!!LOL
I try to watch some of what I eat....ie, dairy and sugar, but I haven't eaten so much as a 3 inch square piece of chocolate in 15 years so I think I'm pretty good. I don't smoke or drink, I get plenty of sleep, and eat pretty much ok, so I'm not sure of the diet thing being a myth or not. And I can't take supplements or vitamins too much because of the lupus so I am not sure what to tell you about that.
Hopefully we will get through this awful time of trial and error and cross over to the other "clear" side of life. I'd certainly hope I don't have to spend another 5 years fighting this! (I'd prefer 5 minutes)
