Think you really need to think about this. I am a pharmacist and did the same thing. Passed PPL, Night, ATPL, hour building and MUlti, IR. Stalled when it came to CPL as it was about two years ago and the industry had crashed so decided to hedge my bets. Stupid really but my ATPL's have now lapsed. TBH doing it slowly didn't work for me as it always took an hour or so to get up to speed after a couple of months lay off between modules. If I were to do it again I would have gone integrated and got it out the way. I sold my house and traded down to a flat and had the cash but just wasn't confident enough to jump in head first, I think if I had it would have worked better.
Gave it my best go and it all ended up going Pete Tong, at least I can sit in my rocking chair and NOT say if only.
Its hard work holding down a responsible job and doing the training.
