If they are 5s try taking 3. Try parachuting them, if your not familiar with this technique, it's so it hits you faster. If you wanna be sure you'll feel it, I would get 3 and a half and break then into tiny pieces and take them. This will help your stomach break them down faster, you should feel this for sure. Good luck, opiates are amazing when you get the effects
dont drink beer with them. alcohol and Tylenol together are very bad for your liver and can cause stomach bleeding. plus u risk respiratory failure. just take a bigger dose. anyway booze ruins the high for me at least.
Don't drink with them. Instead, just before taking them, have a high fat, low volume snack (on an otherwise empty stomach). Half a chocolate bar, one fried egg, etc.
