I need advice. I have been having a multitude of problems since my mother died in March.I have been going for therapy and take Zoloft 100mg, supposed to take 150 mg but I thought it made me tired. Anyway, I am having pressure in my neck and feel like my heart is racing. Also, my stomach is bloated, I have a terrible sour taste in my mouth and my IBS is on and off. I heard effexor mentioned I wonder what anyone else has tried.
