Just pop them both.. just make sure there is no way u could get caught because it seems like if there is any way, that u will figure it out and be paranoid about it. Make sure youre parents arent suspicious, that you wont talk to them, and hopefully that they wont be home. Also, put on some soothing music that you are familiar with and that doesnt have any like depressing tunes or loud scary bursts lol cuz that can start a bad trip.

As long as you guys are in a happy, energetic state before dropping them and as long as u stay that way until it hits you, you will have a great time. Id take 1 hit and let it hit you and if you feel ok with that then take the other...it wont hit you as hard as the first cuz of tolerance so take it as soon as you think you can. Have fun and be safe man
