Somehow this post ended up in 2 spots. I replied to you on the blog Newly Diagnosed but in case you don't find that comment here goes again.
So sorry you are not feeling good. I too have been on 3 x FEC and 3 x D chemo. Am just 2 weeks away from last D. Good news is it does go quickly and it does end!
I found it took about a week or so to get over each dose. Always let your doctor and chemo team know about what side effects you experience so that they can help where possible. I found the exhaustion got better for me after day 5 with FEC. The red face and neck are probably a reaction to the DEX steriod medication that you take for the first couple of days after Chemo.
My hair started to fall about 2 weeks after first FEC. It took a week or so and I found it helped to have it shaved once it started to go. I had a headache at this time and my scalp was quite painful.
Hope this helps and that you start to feel better soon.
Look after yourself.
