Hey fantail, I did feel that way for awhile. I actually still feel fatigued at times at almost 6 months. I am starting to wonder if my body simple cant handle the other toxins I still inject such as caffiene & nicotine. I don't know if you use those but maybe a good question for the doctor? Or try cutting out? Either way it's good you're going to get checked out. I'm getting a physical soon too. Sometimes I think my exhaustion is simply from mental stuff... Dealing w feelings in early sobriety can be quite tiring! Let us know how it goes.
