Woot, when you say you got "sick"...do you mean you vomited or you just felt really bad? I'm only asking because some people use the word gettin "sick" as meaning vomiting.
I know a lot of people recommend that kind of a dose. But, keep a close eye on your freckles. Even ones you didn't know you had will pop up and darken. Mine did at the .5mg dose.
I went .5mg for 10 or 14 days (can't remember now) and then went to .5 2 x per week as maintenance. If you tan a bit you'll get as dark as you want.
The tan is different than a "normal" tan. You tan evenly and deeply. You literally look like you're a naturally darker person.
