No, I avoid Sunny D because I don't really like it, and last time I had it, I puked it right back up about a minute after I drank it.
The thing about Tom Collins is that they mask the alcohol in the gin (hell, they mask most of the gin taste, anyway), so you can drink a lot of them and end up getting way drunker than you might have planned. Same thing goes for screwdrivers, really.
