Woah you go on for 15 minutes AT A TIME? kerazy..hmm i used to go on them but then stopped for a couple of months cause i was worried cause theres skin cancer in my family, but im goin on holiday in just under two weeks so im planning on having about 4 or 5 sessions on a sunbed before i go to build up abit of a tan! Would probably go on for like, 5 minutes at first and then build up a minute or two more each time..i think thats what i used to do! Cant even remember though, the longest i ever had was about 8 minutes! round here its pretty much 50p per minute. About the red patches..are they hot to touch? I got that once when i went on for abit too long, i got home and moisturised throughly and it was fine teh next day, i think i had burnt myself though cause i was pretty pale then. the redness did go away quite fast, like an hour or some3thing but i knew id been on too long! think it was were the rest of me was browner, so that was fine, but it was like the top of my legs that got burnt which were white cause of bikini. Make sure you go on wearing a cream of some sort, they usually provide them sometimes free and there just a moisteriser, or sometimes there around a pound or two for a sachet. The last time i bought a sachet one i was REALLY happy, it really worked and its worth the extra money. Do people find some places they go are stronger than others? And has anyone been in the stand-up ones..i hate them SO clostrophobic and my goggles always fall off!
