I've worked with an organization providing care to the homeless a few years ago, and while being HIV+ is not a short-term death sentence anymore, it is nowhere near as easy to treat as you make it. Most patients can expect to spend about 3 to 7 years using drugs with only moderate side-effects, but after that, most start needing to use some stronger drugs. These can have very serious side effects, including vomiting several times a day, constant headaches, extreme dizziness, lack of appetite so bad that they have to force themselves to eat every meal, sexual dysfunction, etc.
I'm not a medical professional but from what I understand there are also strains of HIV that need the "strong" treatment right away, and people can even get multiple strains (I saw a few of those). Even with the medication being free in Canada, where I live, I spoke with people in their late 30s who stopped taking the meds because they'd rather have a few more years of relatively good life than living with the drugs' side effects.
We've made a lot of progress, but HIV is still a death sentence, just longer term. And you'll feel miserable for the better part of your remaining life. Not something to take lightly.
