Anxiety attacks after cocaine sessions

[F.U.B.A.R]

swim is currently ten days sober from cola, he had a binge that has lasted around 3 weeks he mixes this with alcohol and weed which he knows cocaethaleyne is produced and all the blah blah harm reduction stuff but the last ten days have seen swim becoming breathless and even awaking in the earlier hours short of breath. this then gets quite intense to the point of utter panic. all this aside swims payday is only a week away and that little voice in his head is going to tell him he deserves a treat and the cycle of anxiety attacks will start again. swims mate has said that kava products help with anxiety is this true? and would this help both in the fight against coke addcition and anxiety attacks
