how can i know if i have bad breath?

How can I know if I have bad breath? self-tests??????

Breathe on someone. We all have bad breath from time to time. Do you mean all the time? Try Listerine. If it continues no matter what you try, see an oral surgeon. You may have gum disease. or an infection. I have never heard of self-tests unless you mean blowing into your hand. This is pretty iffy. It is hard to detect by yourself. Ask a friend.

Anxiety or Sleep Apnea?

I suffer from anxiety disorder and am in the middle of controlling it. I usually get dizzy, nausea and short of breath (on a bad day). Lately I have been feeling pretty alright still with short of breath but not so bad. Sometimes when I’m trying to fall asleep I seem to gasp for air, I don’t know if I am actually gasping or just waking my self up. This doesn’t happen every night (that I notice). I live in a basement with one window and think that maybe it might also be becasue it can get stuffy down here. I’ve been keeping the window open a crack (too cold to leave it wide open) and I find it hasn’t happened.
My doctor has requested a test that I put on my finger at night to test my oxygen levels, still waiting for the hospital to call me to pick up the equippment.

Medication like Antidepressants (SSRI – Selective Serotonin Reuptake Inhibitor) helps to boost Serotonin level.

But there are natural ways to do it without medication. There’s this strange herb called “St John’s Wort” – it is said to be more effective than Prozac. No, it is not for mild depression only and ignore those sayings. In fact, it does help anxiety and panic-attacks as St John’s Wort works like prozac. Other natural ways will be exercise, diet, more exposure to light, etc.
The problem is that, even if your Serotonin is balanced… you have that “learned behavior” in your mind. You need to break that initial cycle to destroy that learned behavior – Cognitive Behavior Therapy (CBT) does this. A technique that you can use without CBT will be Distraction… There are several other techniques to help cope them!
Ok, to use Distraction: Firstly, try to….
