how fast does lsd tolerance build up?

I did a search on this but couldnt find an answer to my question. I took lsd a whle back, around one hit of what I was told was "average blotter." I tripped fairly hard (i seem to have a low tolerance to every drug, a bowl of low mids and im blazed as hell), with semi-intense visuals. My friend is getting some gel tabs, which I've heard that on average are more potent than blotters. I dont want to tripcrazy hard, so I told him I was going to just take one at first, and then after the come up, take another if I wasn't satisfied. He told me this was a waste, that tolerance builds up so fast that taking another hit wouldn't increase the intensity of the trip, only the duration. Is this true?

 

hm what i meant was does it make sense to take a hit, and then i guess an hour and a half or two hours later take another hit? would that increase intensity or just make the trip last longer?
