Hello. Recently, I started taking Zoloft for anxiety/depression. After taking it for five days, I discontinued it because I was having a lot of intestinal problems. It was aggravating my acid reflux (GERD). I was also taking Nexium, but I'm finding now, I can no longer take Nexium as it makes me feel ill. I've also noticed I get very ill (tingling sensations throughout my body, lightheadedness and the feeling that I want to pass out) just before a bowel movement. I feel much better afterwards. I know this is all related to Zoloft because I never felt this way before. Please explain what has happened to my body.
