My brother was diagnosed with brain cancer 2 years ago. I already had some of this product that I used occasionally for PMS, etc. It became my life saver for doctor's visits, bad news, sad & stressful situations. I noticed a definite difference on the days I took it and we went to the doctor vs days I forgot to take it. Everything still hurt, but I didn't collapse or go hysterical as the bad news just got worse. It helped me cope with an impossible situation. Dealing with certain family members even now that he's been gone a year is still difficult, so I always bring my Serotonin when I have to interact with them.
If you fly off the handle in seemingly benign situations, can't cope with some people or stressful situations, or just wish that your emotions were less volatile, give this a chance. No side effects, you just weather the storm easier, without crazy ups and downs. Things which would make you want to lash out at someone verbally now still annoy you, but you can hold your tongue. They roll off your back like a duck in water.
I do not say this lightly. I don't know how I could have coped with the last 2 years without this product, and I use it regularly now. Because when does life not get to you unexpectedly sometimes?
