jojo,
I was bleeding very heavily with the UC for 1 1/2 years straight - and the only thing that stopped that was LDN, low dose naltrexone.
I would suggest you look into that. There's a post on the UC resources pages all about it.
Since you are in Mexico, you may be able to find it there as there are so many meds available without prescriptions, but if not, let me know and I'll explain how you can get it.
So you can compare costs, in the US it costs $30-50 per month.
Hope you start to feel better soon.
