Antibiotics question and other stuff

Been on Amoxi(something) for two months...never did anything for me so my doctor switched me to Doxcy and I've been on it for a month and a half and I'm perfectllyyy clear. Problem is...if I skip taking it for a few days I break out badddddd. So everyday I take one. The problem though, is how long can I take 100mg Doxcy before I get resistant? I know it's different for everyone, but on average?

I can't ask my Derm cause he's an ass and tells me to take them foreverrrrrrr and when I ask about resistance he just shrugs it off and tells me the sameee thing. No topical cream has ever worked on me. Doxcy is the only thing that works. My derm won't give me any other pills but antiobitics and keeps giving me topical treatments even though he knows topical treatments do nothing for me. :/ ( Plus he always gives me something with BP in it even though I'm ALLERGIC)

Are there any other pills BESIDE antibiotics that I can take for acne? Because my derm refuses to discuss it with me and either brings up accutane (NOT DOING THAT) or antibiotics. Obviously, I don't go to him anymore and am currently in the process of looking for another derm.

But until then, anyone have some advice on what I can do? Keep taking the doxcy for longer or try to find some other pills?

Thanks.

Water make you breakout?

If in my case, water is the culprit for my breakouts. What do I do about it?

I live in the country. And our water is pretty clean and I hardly ever get breakouts when I am there. The second I leave to go travel and get in the shower, I get bad breakouts.

When I get back home. They go away after a few days after using the water at home.

o.o This is really bad for me. I am going to Austin for college soon and I've been there before and their water kills my skin. Any suggestions for what I can do?

No acne medication has been able to help my skin after bad water has gotten to it.

Question on Cleansers

Excuse me if this is the wrong place to ask, just joined.

But I hear mixed answers on what type of soap I should use on my face. Few people online, along with my dermatalogist said it's best to use mild soaps like Dove sensitive face wash. While others say it's best to use medicated wash like Sulphur soaps and Salicylic acid wash.

Right now I currently wash my face with a mix of Sulphur and Salicylic wash because I heard that was a good combo, but haven't seen any results. ( Been doing that for over a week )

And I did use just Dove face wash before and again, didn't see much results.

So since I don't see any improvement with both, does it matter? ^^;;

What kind of face wash do you guys think I should use? If you had a better experience with one, please tell me.

Lately I've been getting breakouts every day, but it might be because I am currently visiting Poland for a month and the food or water or time change is doing something. I'm not sure if that would make a difference.
