Are some alcohols weaker?

I’ve been drinking the same cocktail for a couple hours (probably had like 4 or 5 of them (personal creation)), it contains Malibu, midori, tripple sec and solo (lemon squash), it’s been an hour or 2 since I’ve had the first one and it really doesn’t feel like it’s hitting

Am I in some drunken delusion or do sweet alcohols just not hit as hard as a non sweet liquor like vodka or Bacardi?
