I had the V-CAT treatment, and if you make a reservation, you have to wait about 20 minutes and the treatment is over in less than 5 minutes. The injections sting, but it is bearable and I don't feel dizzy (in my case), so I can live my daily life. They will ask you which part you want to focus on, and if you ask them to do it naturally, they will let you do it on their own. The effect is subtle, so I want to take it consistently, but the cost is an issue.
