I would agree with Curl…
If you’re asking if you should continue with this drug because of a benefit in curbing your libido via a sideeffect, then I would imagine you’d feel a lot stronger and more confident if you know that you are controlling a situation with your own willpower rather than it being controlled by an artificial drug in your system. Plus, if you were to ever stop, it might cause anxiety to you that you will not be able to control it yourself because it has been controlled by a drug for so long.
However, if you’re saying that the drug works for you in every other respect, and if you should change it just because of this side effect, then you have to weigh up the benefit of taking this drug with the downfall of the side effect…just like if you have a headache but you know the only tablet that will help makes you feel sick, you have to weigh up which is the easiest to live with.
