My Pregabalin experience:
Although I started off at very small doses and gradually increased, I did not at the time realise Preg's rapid tolerance onset. Pretty soon I was taking huge quantities.
When Preg worked, it felt really nice - a pleasant spaced-out buzzed. I doubt it would compare to opiates, but I much prefer it to alcohol which I can barely stomach any more, and Benzos never did much for me.
Problem is, I got to the point where I was consuming eye-watering amounts of Preg - not just a few 300mg capusles, but several grams - yes MANY GRAMS - sometimes in the region of
20 grams or even more of the stuff to feel the same effect!
What's worse, often I can consume this many grams of Preg and STILL feel nothing at all.
Tolerance never seems to reset. I can go for weeks and weeks without popping a single capsule but then if I decide to try again I will still need many many grams, and even then I often get nothing from it -it's really frustrating. I think having an empty stomach may help perpetuate the effects perhaps.
Consuming such huge quantities of Preg at a time doesn't seem to have any immediate negative consequences to me - I don't get withdrawals or anything - although it can make me sleepy - but I am aware that binging on such a large amount of a relitively unknown and new-ish medication is reckless and may have unforseen detrimental long term effects on my body that aren't immediatley obvious (will it wreck my liver for instance?) So it does concern me.
And I'm envious of those who can get the nice effects from just popping a couple of capsules! You're lucky - my advice is beware of the rapid tolerance increasing
