Sorry to hear about that. I had the same thing earlier in the year. First of all, did your doctor do a comprehensive test (not just iron, but blood feritin, B12, and all the rest)? What suggestions did s/he give? If it is just iron that you need, and not B12, then I'm afraid that a supplement is the best way. No excuses here - put it out the night before next to your bed with a glass of water and take it first thing in the morning if that's what it takes! The best ones are the 200mg ones from Boots (you have to ask for it at the prescriptions area). Take three a day for a month, then one a day after that.
Alternately, red meat does the trick, as does veggies such as spinach. Eggs too. Beans, esp. chick peas, have good iron content. Also, you might like to check out a fortified cereal (bran flakes usually have the best iron content) - probably the easiest solution for you, if you really don't want to take the supplements.
