First of all, with 75mg you won't even reach 1st plateau with that dose. I would aim for a second plateau trip, around 130mg to 390mg for a nice more noticeable trip. I've tried the robo gels once and I puked, I usually buy cheaper gels. Don't let this discourage you. Those gels are great and after I puked I felt amazing and the trip was a lot better. Also it didn't help that I did not have weed. Weed helps a ton with nausea and puking so would 100% recommend it. It also enhances the trip so be careful! Do not eat one hour before you dose. It takes about an hour to kick in ( depending on hbr or poly) and when you feel like it is kicking in that is the best time to smoke (maybe a little earlier). Make sure you have nothing to do before you dose, no one to bother you. DXM can also make you itchy so some take Benadryl before or after they dose to combat it, I just ignore it. The comedown isn't really noticeable for me. I did notice an afterglow which was nice the next day and an intense craving to do it more. From my experience I like to lay down on my back or side with headphones on, In pitch black. This is how I get my favorite experiences. Be careful when you dose and if you decide to dose in the future. This drug is nothing to play around with. It is the most addicting substance I have tried ( despite what everyone says). I hope my post isn't too unorganized and it helps you for your first time.
