Lidocaine 5%

I had the best progress so far with lidocaine, I think that was the missing puzzle for me. I couldn’t insert pass intimate rose 2 an even then not all the way but I am able to insert 3 and Dilator 4 like 70% with lidocaine. I wasn’t able to insert 4 all the way but I am impressed with the progress I made with lidocaine in 1 setting. I wanted to ask if this can be used for couple of weeks ? Until I am able to insert dilator 6 and slowly get off it ?
