I faced most of the changes with a smile, apart from acne. After about half a year of T, I got the worst cystic acne at my jawline. It had to be treated with accutane because different antibiotics did not work. Turned out it was probably due to high T levels, but I get where you are coming from. Acne is no fun. Regarding weight, in the first half year I gained 3 to 4 kilos. But I seem to have magically (as in, I don't know how or why) lost 2 of them now. So my gain from start to about a year has been two kilos. I didn't have top surgery, but this is a concern for me as well. It would be a shame to lose the muscles I'm building now, and gaining fat because of inactivity.
