I don't use the bottles, I use the Opticlick Pen. I've been on it about a year, gradually increasing my dose as needed. I've been on 88 for quite a few weeks now.
I only took 82 this morning just in case. As of right now my blood sugar is a disgusting 294. Tomorrow I'll go to 84 and work my way up to 88 by Saturday.
Sorry everphill, I didn't read your suggestion until after my dose. I did use the same cartridge, it was okay, nothing strange happened.
