Hey Crash, ok, first, good questions. You can be curious for whatever reason you want to be, it's cool. Sometimes coming to a place like this, you'll get responses from people and you'll be like "um, what the heck" but try not to let that derail you from finding out what you are trying to find out. As long as you are respectful and are genuine, most people will be cool to you.
So, questions...I thought about this and I have to tell you, even though it's only been three and half years for me, I don't really remember what it was like NOT to be taking hormones. I know I'm happier now, but I really don't think that has much to do with hormones at all. I think it's because never in my whole life could I ever have dreamed I'd be living the life I am living now...and I had a great one before transition. I'm finally genuinely happy with where I am

Oh, back to your questions!
I never felt my muscles weaken or anything. If you get a chance, check out my blog on Susan's in the blog section and look for the posts labeled stuff like "3 weeks on HRT" and "6 months of HRT" because I describe what I was going through pretty clearly. I did notice my neck and upper body muscles going away pretty fast, but I was losing weight RAPIDLY before and during the beginning part of my transition.
I don't know that the physical changes were as much as emotional. I made a blog post recently about crying at work and during stressful situations. That's the kind of thing I probably notice more than physical. I will tell you that I started HRT and electro at the same time. I knew where I was going with my transition and I wasn't going to be derailed no matter what. In the beginning I tracked EVERYTHING!!! My labs, body dimensions, etc. It's all in my blog. I don't do that anymore but I will tell you it was an exciting time because I was hopeful that I'd end up in a good place, better than where I was at the time, which wasn't a terrible place.
Look forward to hearing more from you on the forums. Be well
