As far as I remember this was pretty much a vote agreeing to give ourselves less power within Europe and giving Europe more power over our laws.
"We" wanted some assurances we wouldn't have to bring in abortion if Lisbon was voted in, a few years later we decided to bring in abortion anyway.
The successful yes campaign was telling us we had to vote for it "for jobs" as there was a shortage of jobs around at the time the rerun of the referendum was happening but nobody had any idea how it would create jobs and they never made any attempt to tell us how this would happen. So as far as I can tell this was a pack of lies.
So we voted to give ourselves less power and the EU more, for what exactly?
