Thank you both for the kind words of encouragement and advice! I've actually been doing a lot better since my last update (which is kind of why I haven't been updating - my acne hasn't even been on my mind that much!) - I haven't had any cysts for at least a week or two, and the pimples I do have are drying up and going away. I hope I don't jinx it, but things are looking up.
The dryness did come back - the week I updated was the week I got my period, so I think that may have caused the extreme oiliness at the time. After my period my skin dried right up again. I guess there's no way around the breakouts during that time of the month for me, even on Accutane. My skin feels smooth now save for the occasional bump here or there, but nowhere near as bad as it was a week or two ago. Still lots of scarring, of course, and like ZOSO, my skin is really blotchy when I'm not wearing makeup. Red patches on cheeks and all.
Other side effects, I experienced another headache yesterday, first in a while. I don't know if I'm just really used to the side effects now, but I'm not really feeling it. I'm aware my lips are dry, but it doesn't really bother me, and I don't really seem to be feeling the aches. My skin isn't even flaking so much now, if I put makeup on I look pretty normal in "good" lighting. Again, hope I'm not jinxing anything.
All is well so far. I still expect some surprises from Accutane, but it's been a fairly good to me lately.
