Advice on doing natural supplements for bf

Baby is 7 weeks old, and pretty fussy most of the time. She was always having enough wet diapers, but the fussiness made me worry I wasn’t giving her enough breastmilk every feeding. I have left her on the breast for hours at a time, because she’d be so fussy. I started supplementing with formula because she was only gaining 3-4oz a week. Now she’s up to 10oz gain a week. I am currently doing lots of natural supplements to help my supply and hope to quit the formula. Is it possible to do TOO MANY natural remedies?? Daily, I am eating 2 lactation cookies, 2 packs of oatmeal, 2 mothers maid teas, chugging water until I feel sick, non alcoholic beer every few days, and goats rue. Should I cut back? Any tips would be great!
