Yes, but I've been doing 11-12 hour days for months + commute time of 30-60mins each way, getting home, having dinner putting the kids to bed and studying from 8pm-11pm as often as I can, sometimes working 6-7 days a week. Every week I seem to get a cold and I'm constantly dosed up on day nurse or ibuprofen, my boss has even got concerned and suggested I take euthanasia echinacea tablet too boost my immune system.
F@ck it, keep plodding on. After all it's only going to get better, right?
