Hello and welcome to our community
Hmm, it does have different effects on different people. Before using the pump, I was on insulin injections, and Meformin 500mg tablets. I took 2 in the morning, and 2 at night for a total of 2000mg per day, with no problems. Now I'm off of everything except the pump, and a different insulin.hi i have used metformin hydrocloride (liquid solution to it) I honestly think it doesnt work as i still felt hungry and was already taking my 10ml max dosage and gave me very bad side effects that resorted with me not being able to leave the lavatory...... bad stuff
