Let me correct myself. You do not need to CWE the Ultram, it has no apap, I was thinking about another form of tramadol.
Take about 200mgs of tramadol.
Take a couple of Fioricets, but not too many. (nothing over 900-1000mgs of apap.)
Three is safe. 975mgs of apap is in three Fioricets. 120mgs of caffeine is fine(and normal), it will make the drugs flow faster.
Since Fioricets are not that strong at all, and tramadol is not that strong at all, they will both take effect and get you good and high.
If you have any kind of opiate tolerance you can easily handle this combo.
