Scootey,
First off, your doctor that told you fatigue isn't a symptom of haemochromatosis is an idiot.
Fatigue is the biggest giveaway of having high overload so don't you dare listen to them. When I first started my iron level was only at about 600 so that's around half of what yours is. I was told I would need phlebotomies once every two weeks and I needed to have that done for two months before it changed to once a month, once every six weeks, once every eight weeks, etc. (just for your reference, I was diagnosed in 2010 when I was 21 and I'm now 24 and I rarely need phlebotomies anymore - this could be due to my young age and my body adapting very well to treatment because zero damage had been done to my body).
I completely understand your plans falling through, however. I can't remember the last time I wasn't tired all the time, it's so, so awful and everyone just thinks you're being lazy or exaggerating but when it's your day off and you sleep in until 2:00 unless someone wakes you up, clearly something is wrong.
I can't say how long you'll need to get them done all the time, it really depends on the person. Like I said, I only needed four phlebotomies once every two weeks for a period of two months before they extended my time in between. Is the force that you work on accommodating to this at all? I'm not sure where you live, but one of the outpatient clinics that I go to does phlebotomies as late as 7:00 pm and they begin them at 7:00 a.m. so it's easy to work around your work schedule. Do you have anything like that where you live?
And what kind of side-effects are you experiencing from them? When I have my phlebotomies, first off, I need an IV because I drain so fast and I'm a petite woman (just under 5'4'' and I'm 121 lbs) so the amount of blood coming out of me is just too much without so I'll pass out, but other than that I feel pretty much fine afterwards. A little bit light headed for a couple hours, but then I'm alright. What symptoms are you experiencing?
In terms of working blood tests around, where I live we have Dynalife and you can make appointments at lunch time, over the weekends, etc. Is there anything like that around you? How much research have you done and have you pressed your doctor for resources? There's no shame in being pushy and explaining your work situation.
In the end though, as much as it sucks, sometimes your work has to suffer for a short period of time. It's so, so important to take care of this asap and nip it right away so that you limit the amount of damage done to your body. I was lucky as the law firm that I worked at at the time was very nice about me leaving early and having to get them done. I really hope that the force you work on is very understanding. After all, the sooner your levels drop to a good rate, the better you'll be on the job, and that's important to not only you, but them as well.
Let me know!
