I've been taking 500mg/day Metformin for the last three years. The doc who diagnosed me moved shortly after starting me on Met, and the doc to whom he referred me kept saying "let's hold off on that" when it came to increasing the dose (my face was cleared up and hair growing back, but no weight loss at all and my periods only controlled by BCP). Finally, when my face started breaking out again out of the blue, I found another doc who could say "PCOS" without a question mark, and she immediately bumped me up to 1500mg/day.
Within a couple of days I was suffering from extreme fatigue and anxiety, and it just kept getting worse. My description of being exhausted all the time was blown off, I think because she thought I was making excuses for not exercising more. After two months, I ended up firing her and going to see someone else who was horrified to hear I'd been bumped from 500 to 1500 literally overnight, and who immediately halved the dose, although she couldn't believe the anxiety was caused by the Met because it's not a published side-effect.
Few days later, I accidentally popped a second pill after dinner (as had been my habit before having the dose reduced). Within an hour I'm exhausted, anxious, and achy all over. I couldn't sleep despite being exhausted, so I started researching... and came up with lactic acidosis.
This was yesterday. I have a horrible metallic taste in my mouth still, although the anxiety is abated. I'd hate to think what condition I'd be in now if the dose hadn't been halved a few days ago!
So assuming I'm right about it being lactic acidosis, it also solves a much longer-term puzzle for me. For the last three years (and I didn't realize the time correlation until now), I have tried getting into a regular exercise routine, only to find myself becoming increasingly fatigued as the days passed and finally becoming sick so I had to stop.
I'm weaning off of Metformin ASAP. I think it's pretty clear this is the wrong route for controlling my PCOS. What to me is most scary is that everyone missed it.
So yes, I'd agree that lactic acidosis can come on much slower in some people, and that it may have a cumulative effect over time. I feel so much like I've dodged a bullet... |
