Advice, opinions, just plain old help lol!

Hi ladies, I have a question for you all and I'm not sure if anyone is in the situation or not but any advice would be greatly appreciated.

About 13 years ago I started to have asthma attacks, they stop after 6 months and I haven't had one attack since then.  The only thing I have been left with is a chronic cough.  I went to a pulmonary specialist in 2006 and he told me I have cough variant asthma.  I have been taking on and off since then the usual asthma medicines.  About 6 months ago I stopped everything.  I never had any relief from any of the meds and I figured at this point it wouldn't make a difference and it didn't.

About two months ago I decided to go to another pulmonary dr for another opinion.  I couldn't imagine having to go through the rest of my life with this annoying cough.  Well on Tuesday I went to the new dr who is younger, really listened to me and took notes while I was talking.  She said there are 3 main causes of a cough.  One is asthma, post nasal drip and acid reflux.  I told her I don't have any symptoms of acid reflux which she told me it can be silent reflux.  So she said because of the twins, I could be experiencing more now.  Anyway - she said she wanted to treat all three and since I was in my first trimester this is all she could for now.  

First, the coughing will not hurt the babies right now.  Her concern is later on as the twins gain weight, the coughing, will push them towards my cervix and cause a possible premature labor.  So she wants to take care of the cough now before then.  

This is what she suggested - use a neubulizer with albulterol 4 times a day, zrtec at night and tums 4 times a day.  She then says you should have no cough in about a week.  I have a hard time believing this because if this cough actually went away finally, I would have to erect a statue of this dr in Central Park! So she says to me this is all safe to use during the first trimester and to go ahead and check with my dr if I feel better.  If he doesn't agree, we can adjust this.  

So yesterday I called the RE - got the nurse gave her all the info and she said I'll check with the dr and call you back.  So she does and says that the zrtec is fine.  The tums should be taken 2 hours after medications because it can interfere with the other meds.  The albuterol is generally not safe but because you are asthmatic you have no choice.  So I try to explain to her I haven't had an attack in over 10 years, explaining everything but she said well the dr. says you can take it because you have to.  UGH.  So I really didn't know what to think at that point.  

I decide to call my obgyn office and ask them as well.  The nurse says at first - I don't think you should use the zrtec during the first trimester.  Then she says who is prescribing this to you??  I said my pulmonary dr. - so she says oh then if she says its ok, its ok.  Really???

What the heck?? I feel like I didn't get conclusive answers.  I know the albuterol is a class C drug.  I am not sure what to do.  I mean I can suffer with the dam cough like I have been at this point.  

What would you ladies do??
