Solution - elastoplast?

So I've been looking around on the internets to see if anyone has had any success kicking this thing.. and I found something that seems promising. It's called "elastoplast", and it's a clear plaster that you spray on cuts (kind of like nu-skin?). But apparently this is nearly invisible, flexible, and stays for about 2 days without washing off - sweet! It's only sold in England, and I just ordered a can online last night.. should be here in a week or so. I suppose I should say here that my picking is centered around the sides of my nails on all fingers. So!- the plan is to spray it on all fingers but one or two, and repeat every two days for a week or so, just to see how it goes. After that, all fingers for a month straight! This is how long I hear it takes to make or break a habit. I'm pretty excited about the potential, but have some concerns too. Like what if I just relocate my habit elsewhere? And what if this isn't really the same as a 'habit' you can just kick? I'm still gonna try it out though, and I'll definitely make updates on progress (hopefully!) being made :)
