Sorry this is 2 years too late for you, but for the record the only thing Sentia gave me was an upset stomach, they did tell me not to drink the whole thing so I took it as a challenge. Wish I hadn't bothered. Stomach pains, some other odd effects to mood that were subtle almost to the point of nonexistence. There's plenty of alcohol replacements available in the... other.... part of the market but if this it then I don't think alcohol has anything to worry about. I'm curious as to whether Mr Nutt has either not tried his drink at all, or perhaps he's been trying it a bit too much, and in his addled state of mind, decided to send out this. Everything about it is deceiving. The marketing is straight up misinformation, this is just a few nootropic compounds and herbal extracts in a bottle - sorry, Proprietory Gaba Blend(TM), I expected a lot from David Nutt, his goal is an excellent one and I'll probably still end up buying whatever the next drink is that he puts out, just because I would love to have an alcohol replacement, maybe I should send David some pregabalin, he needs to put something a lot stronger in that drink if you want to have even the slightest hope of making a dent in the competition.
Sentia = stomach cramps, very subtle Ashwagandha-like feeling for about 2 hours, and that was it. It did taste good tho I must admit, it's just a shame I didn't buy it for the flavour. Really hope the next iteration is not more of this.. Will have to wait and see but until then I would recommend giving Sentia a miss, but that's based only on my own experience, of course everyone is subjective. But (sorry Dave) Sentia is overpriced shit with deceptive marketing that is not able to deliver anything remotely close to the product they seem to think they have. I know, I know, it's their first attempt in a pretty novel field of study, just hope V2 is something new/a complete overhaul, not just Sentia 2, now with 4x the Ashwagandha. I guess time will tell. In that intervening time, best take your hard earned currency units elsewhere for now.
