Choline\5htp\Melatonin (Questions)

Okay,I just want to get some feedback on these supplements because I was wanting to know if any of these 3 things are good paired with each other...my choline are 250mg a pill, my 5 htp are 100 mg, 5mg melatonin. I didn't find any threads abouts choline with anything else other than piracetam or galantamine and i have no plans on purchasing these because I could LD every now and then naturally w/o any help before I stopped but now I am back and need some reviews on these relatively cheap supplements...any help is appreciated...DeXtRoChRiS!!!
