I've been taking pregab recreationally weekly for ~10 months, and finally just started to notice a tolerance build up. After experimenting with complete GABA tolerance breaks I'm happy to report being near back to baseline with prega after 1.5 months

, I had a 1 month break, then required 600mg to get high on pregab, then another 2 week break and 300mg is enough to get me back to baseline (woohoo, very happy!). I'm going to take this as a warning to not exceed once per fortnight dosing, but given how much I love this drug I'm willing to extend to monthly to protect the high.
For background and experience info - I'm 300lbs+, I usually take 300mg orally very early in the morning so I can enjoy the full duration of the pregab (it's a dose I can take without people noticing I'm on it!), though I experimented with 600mg and 900mg a few times (which are both very fun). Insufflation is a much more intense experience than oral, but I will at time mix both ROAs to tweak the experience I want, I'm using pregab insufflated effectively as a a combo with pregab orally because insufflation is much more of an intense experience. 900mg insufflated provides visuals at times similar to mild geometric s-ios ketamine, and a much more intense body feel, shorter duration. Typically if I redose pregab it's just once and it's 300mg insufflated, that's generally done and timed so they 2 doses peak at similar times but trail off towards the end of the day allowing more sedative combos later.
Any advice from people about what's best to do with usage frequency? pregab is my fav drug and I really don't ever want to build up a tolerance to it, would like the fun to always be there if it it mean long tolerance breaks.
EDIT: to add I noticed the tolerance build up because before my GABA break on my last use of pregag I didn't get high on 300mg and required 600mg to get the effect I wanted, I took this as a red flag and stopped using pregab straight away, going cold turkey, and suffering zero withdrawal effects (I think, though have had some sleep issues which I think are stress induced).
