I never experienced the night sweats, but like any medicine it can affect people in different ways. After a while I promise that the medicine will make you feel A LOT better. It takes around 3-4 weeks to kick in, so give it some time. I promise you it really does help. I'm sorry to hear about you waiting for the HIV results, I know that that can be nerve wracking. I hope it all works out. And dont think that you are driving people nuts, because in the end the people you love and that love you are only going to want to help you. I know I probably drove my parents and my boyfriend crazy this past summer, but you honestly need those people to help you get through it, I don't know where I would be without them.
I hope that your feeling better and everything goes well.
