Sorry to hear about your problem. Since everyone is different, your buds may not be set up for SnV.
The recipes you posted are well rated. I have no use for SnV, so I can't make any suggestions.
One recommendation, may make a difference, would be to let all mixes natural age (with an occasional light shake) for at least 4 weeks. The more recipes I make, the more I have in the hopper to test, the more successful I am. It only takes a 2-5% success rate to line up quite a few dynamite recipes.
With this approach, you will start to know which flavors/sometimes brands work for you.
