It's funny that you should say that because I interpreted the thing about not experimenting with doses the other way. I see that it could be taken both ways, as not wanting to go up, or not wanting to go down. I took it as not wanting to go down. I normally use drugs.com to check on doses. They have this as their normal doses. If someone weighs over 30 kg, then it's 600 mg AZT (drugs.com link). And with Raltegravir it's "For the treatment of patients with HIV-1 infection, the dosage of Isentress is 400 mg administered orally, twice daily with or without food. (drugs.com link)"
