Not a fan of pens - just saying!

Just a rant....I did 3 months on vials and lost 15. I changed insurance in Jan and have to do pens. I've done 3 months on pens and as of today - I've gained 5 lbs those 3 months! With vials you push the meds for 5 seconds and know youve gotten it...with pens its like 1 second and I'm not convinced it works lol.
