Intestinal ulcers. With daily twice?

I am on treatment for intestinal ulcers wherein taking Mesalazine 1.2 g daily twice. However suddenly I am facing a problem of bleeding n mucous in stool I am in Australia now and not getting proper Indian diet. Dr had asked me to continue Mesalazine daily once after course for 1 month however since bleeding started I am continuing daily twice. Pls advise is it ok if continue more time with daily twice? Currently daily twice also not seem to solve issue of bleeding immediately. Pls advise on diet to be followed as I am not getting Indian fruits and leafy veggies here. All I am eating is less spicy chicken, pulses, mushrooms, Potatos, spinach, collyflower, basa fish, broccoli, zucchini Greek yogurt and frozen chapatis
