No, I haven't had any other symptoms.
No other symptoms? I'm going to go against the grain here and suggest that you are probably just fatigued.
My other advice is to ask a real doctor either here on SB in the Ask Dr. Deco forum, or on the phone. Only fatigue and no other symptoms would suggest to me that you're fine, or what some may call sub-clinical DCS? But I'm not a doctor, and I didn't see any responses from any doctors. While people are giving you advice that works for them. The rest of the picture is this:
What is your physical condition? Do you exercise regularly? Lift Weights? Cardio? Are scuba tanks heavy for you? Are you carrying doubles? How much physical exertion is required to exit/enter the water? What was your Hydration? Did you eat a good breakfast? Were you Warm / Cold on your decompression? Did you have alcohol the night before? Did you sleep well?
I see you mention you've been cold on the hangs, and that certainly should make you add time to your hang, as vasoconstriction will reduce offgassing. Sounds like you may need to look at better thermal protection as well. Being cold for a half hour makes me tired also.
There are many factors that effect the body. Once we think in our minds that we may be doing the wrong thing (decompression wise) then we over think it, and potentially work ourselves into a "oh crap I might be bent" semi panic state, and make things worse.
While there's nothing wrong with some of the overly conservative advice others are giving you. The answer may be in the questions that I've posed to you here. You could be doing everything "right" by the book (deco wise) but not doing everything right for your body, which the "book" doesn't necessarily take into account.
