It sounds like your DH is the carrier if he announces he has it first then a few days later you get it.
The thing with probiotics is that, taking them here and there doesn't keep it from coming back. Probiotics are a commitment, AND knowing which probiotics to use is the biggest key. Each brand has different strands of bacteria in them and each strain effects different things. Some strains that target yeast are, lactobacillus fermentum, and lactobacillus rhamnosus. I realize that you can go to any pharmacy and find on their shelves packaged probiotics, I'm just going to say that I wouldn't waste my money on them for a couple of reasons. 1. they are sitting on a shelf at room temperature. 2. they are such small doses even if the bacteria is still alive after sitting at room temp like these companies claim, there wouldn't be enough for a candida issue.
You need to get your probiotcs one of two places, a local vitamin store that has them in a cooler, or online from a place that has them in a cooler and ships them with cold packs. Here are the two reasons to do that, the bacteria in probiotics are in a sort of suspended state when kept cold. once introduced to the stomach and a temperature increase they wake up and get to work. If they are woke up in packaging, they die quickly due to lack of food. It doesn't do you much good to get dead bacteria. The second reason is the amounts. The room temp packaged type you get over the counter typically only goes up to around 1- 5 million CFU. If you have any type of health issue you really need 15 billion or higher CFU's. I know many people that probiotics have done wonderful things for, when they finally found the right ones. My mother buys her from a company in Europe, that makes one with 400 billion CFU's for people with colitis. She has now been in remission for 1 year for the first time in 20 years. A good friend of ours developed yeast all over her body and after weeks of the doctors giving her creams and pills, she finally called me and asked me what to do. I sent her to get a high dose and she was clear in 3 days. I myself am a user and huge fan of them also for almost 2 years now. I had yeast and vaginal infections so bad I was getting desperate. I had never had problems and suddenly I couldn't stop getting them. I tried probiotics and was clear in a week. I will warn you though for anyone that is dealing with yeast, when you finally take the right amount of the right stuff, chances are high that you will suffer something called die off, which usually comes in the form of profuse mucous beginning to pour from the nose within about 30 minutes of taking your first dose sometimes. This can last for about 5 to 7 days depending on how badly you were invaded by yeast. Don't worry though, you won't feel like you have a cold. See, the problem that most people don't realize is that candida loves the sinuse cavities. It's warm, it's moist and it's dark. In other words, the perfect hideout when you've been trying to treat it. The good news is that it can't hide there from probiotics!
The last thing I want to say is that whatever route you decide to try to stop the thrush, your husband really needs to do it with you. Taking the right stuff won't help you much if you can't get your husband to take it as well, because he'll just keep introducing it to you. Yes, if you stay on the high dose probiotics chances are you won't get it very often, if any, but there is really no sense in getting rid of it in one and not the other.
