SWIM's first exp was by himself (he's a long time user of psychedelics) and pretty much as soon as the smoke hit his lungs the thought flashed across 'oh fuck should have waited for a friend!'. However, he soon didn't care about that and it all went swimmingly.

I'd say you should think long and hard about doing freebase d even if you're well experienced in other drugs so doing it alone will probably be ok. If you're not prepared then having someone there aint gonna help you that much.

I like having someone to make sure it's all good with el pipe etc. Not long ago SWIM awoke from a d induced slumber to find he'd burnt a hole in a cushion on a solo mission, that could have easily led to trouble.

Also, I find it's good to have someone there simply to rant to about how amazing it was.
