I suffer from a chronic medical condition that requires me to take a certain medication. This medication is required for me to have a healthy physical lifestyle; not taking it would put my physical health at risk and complicate the handling of my condition. For many years, I went without this medication and my physical health declined dramatically as a result; however, I was able to work happily, so it wasn't much of an issue to my employer or my coworkers. Recently, however, my doctor told me that I must continue using this medication. I sought out a second opinion from a different doctor and she confirmed that it would be improper for me to not take this medication, especially if I want to reverse the degradation of my condition.
In short, taking this medication is a must and to not take it is not an option.
However, as I've started taking this drug again, I've started running into the side effects pretty hard. Among the side effects is fatigue and nausea, which I have been feeling since I started taking the drug. These side effects are supposed to lessen and fade away over the course of a few months as my body acclimates to the drug, so it's not a permanent thing. But in the short term, it is definitely affecting my ability to work. Lately, I've been suffering from random episodes of extreme brain-fog and spaciness. It makes my job (computer engineering) very difficult when this happens. I don't really have control over it; coffee can only do so much!
I haven't shared these details with my boss nor my coworkers, and I'm not certain if I should or not, or how to bring it up. Any advice?
