It doesn't sound like you want much more advice, so this will be my last - are you concerned about your iron levels? How's your hemoglobin? What does your doc say - at what point should you move to injections? that sort of thing. You can get iron injections as well as B12 injections. Has your doctor wanted to rule out ulcers as a source of blood loss?
Good luck, and of course feel free to whine.
