i was on 2 a day for years and years (pork mixatard, then after a couple of years pork mixatard in the morning and lenatard in the evening i was then put on 4 a day novorapid and lantus found it hard to get on with and couldn't get good readings then went back to 2 a day, couldn't handle the strictness of it, then went onto humalog and levemir, then the levemir stopped working and then went onto lantus and humalog which i'm on now and it works good. 2 a day is easy when your a kid and at school and have a strict timetable of what you are gonna eat etc, but having a job and socialising etc its hard 4 a day is a pain but so much easier
