It's a drug with no disturbing side effects when dosed correctly. There is no liver damage cos of the low toxic value, no hang-over or water loose, no calories.
Mentally it provides a sensitive warm feeling of intimaty and a strong desire to satify physical needs such as eating and sex. Which is also enjoyed much more intensly.
It doesn't really matter where you do it, at home or a party. Both has it's own unique effect. The effects are somewhat similar to alcohol but no agressiveness, lost of libido, disturbing erectile disfunction. Empathy for others and visually the same perception as being druk.
When listening to your fav music you might experience waves of feelings similar to XTC, but way more emotional especially at higher dosages, tho with no speedy feeling, but totally a relaxtion in every muscle (incl. genital zones). You might cry for no reason, which feels like a release afterwards.
You want to touch others, be with others, understand others, basically you want deeper contact emotionally, sexually, physically and interact on a more intelectual level.
The dose is essential, too low will not produce the maximum G effect, but a high euphoric dose is quite close to a rised sleep as well.
When overdosed a little, let's say 1,5 ml GHB or 0,5 ml GBL above your prefered dose, it's fairly safe to say one will wake up after the half-life period is reached, if there are no other downers involved.
The best way to estimate your dose is to do it at home first, you can stick with your dose since there is no tolerance, unless if abused daily.
Kick off with 1 ml GBL or 4 ml GHB, when feeling fine, you can increase GBL up to 1,5 ml or 5 ml GHB. (Of course the next time, not stacking!) If that dose is doing fine, make sure you stick with it and make seperated portions before you're going to a club or party. (In a ballon for instance)
Drinking it out of the bottle directly or just putting a blind dose in your drink can cause dangerous and very unpleasant effects. Such as losing heartrhitm or even a fatal heartstroke.
For me it's typically a club drug for music styles as techno, trance or house. Tho Goa also feels fine.
