Yes of course. I only took one a day but they increaded my anxiety, I was getting more wound up and speeded up each day. I was also sleeping very heavily but it was not a nice sleep, too deep and full of weird dreams that left me waking tired out. I had reached a point of stability so I felt it must be affecting me.
It did help my bowels and I don't know how they will react to me stopping it but hey ho.
