can anyone recommend me some instant coffee with mild strength?

i recently tried to have coffee around 7am for boost in work/study.
Had tried nescafe white coffee and only can take half pack a day..if 1pack overdose (cant sleep)

now switch to alicafe 5 in 1. with tongkat ali,ginseng...1 pack per day. slight overdose for me (feel anxious and easily irritated in the morning) and cant drink it everyday. btw the taste is great since i mix it with 1 pack of instant milo 3 in 1.
