This doesn’t always work, but I use the ones that have a lemon flavor and promise not to have any aftertaste. The ones with lemon and the “no aftertaste” ones usually really don’t have an aftertaste but the keyword is ‘usually.’ Sometimes there still is a fishy burp about a hour later. Another option is to take the 3-in-one-Omega 3 pills (fish, flax and borage oil), again with a lemon flavor. It’s still a 80–90% hit-miss. The fish-burps still are not as bad as the Omega 3 peanutbutter I bought—first few dabs… perfectly fine Jif-like taste, then one day I took a bite of my toast with pnb, and…fish. Bit again… FISH. what the… sniffed the jar and it was a weird PNB+fish odor. GAG. Never again. Those Omega-3’s are not worth forcing an acquired taste for breaking my fast with PNB+fish. Beware!!! IF you find a perfect fish oil pill, let me know!
