My wife and I have been on it for almost 4-5 years for our asthma / allergies. Just got it refilled. However, over the last couple of months we have been very irritable and stressed. We figured it was due to a new baby in the house. However, last night we discussed that maybe Singular was causing this and the newest edition to the family is just bring out the side effect more to our attention.
