I've been to get the Ranitidine today. Its strange, as last week, I had loads of acid, then 3 days ago I didn't have any acid all day, but then, the past couple of days I've had so much stomach and intestine pain its been a nightmare, I wish it was consistant so I knew what I was doing wrong. Hopefully it was a side affectof the fastab and changing to ranitidine may help, not sure if I've got some sort of infection further down though, knowing my luck It'll be worms or something lol
