Hi, As is always the case, it depends on the context. If you just want to make the basic statement that you like to have more time it is fine to phrase it as follows: I'd like to have more time but I don't. You could also add a word to express regret so that you give a little more emotional content to the sentence: I'd like to have more time but unfortunately I don't. I'd like to have more time but sadly I don't. If you wish to provide more information about why you do not have enough time you could add 'because' to the sentence and then a clause that provides more information. I'd like to have more time but I don't because I have to work. I'd like to have more time but I don't because I have to go out. If you want to use 'I haven't' or 'I don't' then it would be best to place them at the begining of the sentence so you could have: I haven't got enough time.... I don't have enough time.... Hope this helps? Jason.
