Smartphones are the devil.
Okay, bit harsh. Smartphones are undoubtedly very useful. The “I got lost” excuse for arriving late is not valid anymore – a quick few taps in your mobile map app of choice and you can instantly find out where you are (and where you should be).
In terms of good mental health, however, smartphones are one of the fiercest opponents I have encountered. It isn’t necessarily the magnitude of the effect they have on my mood. It is the smartphone’s ability to cling to my brain like a leech. They are almost impossible to remove once latched. The short, sharp and seemingly neverending rewards smartphones offer are intoxicating. And this is putting it mildly.
When I first started to take lithium, I wanted to calculate my peak serum concentration using my 12-hour sample value. I knew it was going to be a very rough estimation, but for me, doing the calculation made me feel less anxious about toxicity.
My plan was to use the exponential decay formula to find the peak concentration (assuming the peak occurred around five hours). I wanted to find out, given I knew my serum creatinine levels, what my approximate lithium half-life was. I went looking for data in the lithium pharmacokinetic literature to figure this out.
There are very few upsides to living with a severe mental illness. One of them is quite a bit of free time. Previous times the clocks have gone back have been a nuisance to me. Especially since I started taking antidepressants. For whatever reason, my brain is very sensitive to the time I take them. If I take my dose late, even by only half an hour, my reality is thrown from side to side like a ship in rough seas.
To be taken safely, my medications have to be taken a set time apart (therefore at fixed intervals in the day). This means that twice a year the time I take my medication shifts by an hour each day. Why don’t you take your medication at the same time all year round? I hear you ask…
