I'm on 20 mg of cuprilex and 100 trazodone, if i forgot to take them one night, is there consequences?

Not really, BUT...: If you miss one dose of these medication, you should be fine, but know that for the medications to be most effective, they should be taken as Prescribed daily. Try to remember to take them every day. Use a weekly pill container if that helps, or develop a routine for taking your medications so you do not forget them, Best wishes.
