My doctor is a good doctor she is a great listener. Medicine is a hit and miss process for one to undergo. Singular worked great to keep the asthma at bay. Yet, there was a down fall that my doctor did not expect. I was having major mood swings. Such as anger, sadness, depression. Once I added Singular, it didn't come until the second month. I know myself quite well I am funny and very loving. This change came like a thief in the night. I woke up one day not standing the sound of my family voices and felt angry. I was crying and feeling sad to the point I was just waiting for the next mood to come. I do know the difference us women have with moods. This was a different degree of a mood swing. I been threw ups and downs so life was not the problem. I notice this change and immediately told my doctor. But, also I was on my rescue inhaler and a steroid inhaler. I believe it became like a combine cocktail of drugs. This combination cause me to feel this way. I got off the steroid that I was taking and Singular. I notice in just two days I am more patient, happy and so is my family. My doctor has me on new meds now and hopefully this well work. Please, as soon as you feel different don't wait seek your doctor's advice immediately. Good luck to all who suffer from Asthma. May there be a cure one day. Thank You, S.
