3 months later and I've only moved up to 25.5 from 23. Well, I didn't take enough, and have only been really taking it seriously for 1 month. I might have to switch to D2, since I can't take too much D3 without getting insomnia, and I clearly need to be taking more. I might try upping my dose of D3 cream one more time and hope I don't get insomnia, but if that doesn't work, I'm going to have to try D2 and then test again in a few months. To be fair, I'm now taking 2000-4000 a day via the cream, but that's a recent development and my body needs more time for it to work. Anyway, I'll have to see. Just thought I'd update.
