My basal is Semglee which annoyingly isn't available with reusable pen. I really dislike the amount of plastic waste this generates as unlike Novo Nordisk, they have no recycling scheme. So looking to move to an alternative Glargine when my current supply runs out. I believe the main alternative brands are Lantus & Toujeo, so just curious if anyone has experience of switching from Semglee to one of these or vice-versa?
