Eat an orange just before you peak. A BIG ONE. That is one of the greatest experience ever. Do it messy, tear into it like a savage, don't wipe up your mess, just eat it like it's the fruit of the gods. It will be.
If you do shrooms by yourself, you could bring your own trip down if you are the type of person who gets bored easily or if you like socialization. By the same token, no matter what type of person you are, if you do it with the right people, you will trip twice as long and may experience exact paranormal events simultaneously such as telekinesis and telepathy.
In one night on the outskirts of San Jose, a group of friends and I all watched Queen Elizzzardbeth turn into a reptile on TV. This was before I was into the whole lizards rule the world bit. That same night I moved a glass of water to my hand by thinking, 'I'm thirsty' ... My girlfriend read my mind and said she was going to hand me my glass. It moved about 2 inches. There was a condensation trail. I had three grown men and myself, as well as my girlfriend crying with disbelief after this event.
if you really want freak out smoke salvia like an hour to two hours after you eat the shrooms.
As a long time cultivator and neighborhood shaman working mainly with Salvia divinorum, I don't advise this. If you are inexperience with either substance, in disturbing or unnatural setting, or not at ease mentally it could potentially disturb or damage you mentally to the end of your days. (this includes people around you. bad vibes)
If you are going to do it, make sure you are NOT INSIDE OR NEAR ANYTHING THAT WILL BREAK! Don't do it someplace high, stay sitting on the ground or low chair, away from water (even a small pool). And make sure someone is there to take away your burning pipe/bong and lighter. I advise not to do so with anyone you don't have complete trust in. I mean like someone who'd help you lube your ass and pull out a 2foot long constipated shit from your body, then wash their hands and treat you to a jamba juice. Seriously.
Salvia is not something to trip on. It is a tool to see inside the real you. And some people don't like the real them, or they haven't contacted themselves and this could change you.(for better or for worse depending on your personality and how you present yourself to the world and other people) It will intensify your mushroom trip like nothing on earth, but Salvia triggers a lot of memories, fear, and anxiety if it is not used properly.
DO NOT LISTEN TO MUSIC WITH MALICIOUS VOCALS while on salvia & shrooms (such as hardcore rap, death metal, or radio pop/hiphop or punk.) ONLY INSTRUMENTAL (preferably natural instruments like drums, strings, and pipes.)
Meditate before doing so. Practice controlling your release and retention of kundalini. Take several deep breaths in preparation for the journey. Then smoke, although the trip would be more passive and not so fearful if you chewed(without swallowing) about 23 leaves for 10 minutes.
Don't buy the extract. Its crap made with acetone and naphtha. Grow a plant and use the leaves. And please be over 18.
