I had ulcers as a kid. For me the symptoms were a strong pain in my midesction(breadbasket area) that made me want to buckle over in pain-especially after meals. I'd feel like drinking milk to coat my stomach, but it only made it worse. I imagine any kind of roids that wind you up emotionally could lead to ulcers, but chances are you'd get them eventually anyway. All you can do is try to relax and stay away from greasy/spicy foods. Beware of drugs like Tagamet-impotence is a side effect.
