I went to a neuro for my prolonged neck pain which he then diagnosed as C-Spondilitis. But the level shown in MRI was mild according to him and to avoid surgery he referred me to a Psychiatrist who prescribed me with Serta (started with the mild dose and then went till OD (Once a day) dose) over a span of 2 years from 2007. I was taking it till 2009 / 2010 and stopped my doctor visits and taking Serta-OD suddenly (got tired of the long treatment as well ass my neck pain reduced). Will this (stopping serta suddenly) have any negative effect in my life in future. I was diagnosed with Irritable Bowel Syndrome in 2012 and not sure it has anything related to this.
