I used to take me 40 minutes and once it truly almost came back up. My new trick is to have a 1/2 lemon handy and I lick it after chugging the SWF, like a chaser. I can get it down muuuuuch faster and am not afraid of it coming back up. My stomach is still a little queasy after but that's not so tough to deal with.
One option is always to do the tea in the morning instead.
