I don't have personal experience, but I've seen an interesting documentary lately in which several people tried ayahuasca. There were two guides with them, one of them was called a shaman and there was someone else too. They both gave a lot of these 'workshops' every month in the Netherlands. Some people thought it was very helpful and transforming, but going through the process was tough. Afterwards most of them were happy and felt relieved, but during they could see things that were traumatizing or shocking for them (some people said they saw how they were conceived or how it felt when their mom gave birth to them and some saw the universe come into existence). The therapists said that it was very impotant that if you try ayahuasca that you do it in a save environment and with supervision. Some of them had to puke a lot and a lot of tears were shed. They really appreciated the help from the therapists (the shaman and his wife were also therapists and coaches for profession, who did this too) with the process (they would hold their hands for example or help re-enact). For some people this experience with ayahuasca was too much, if they were too scared to relive certain moments (that's what the therapists said). So sometimes it would go wrong, but that's why it was important (accordding to them) to have (experienced) supervision around, who know what it's like and what the side-effects can be. If they weren't too scared, it could really help them. I hope this information might help you. I think its really important to decide if you have a good location (and time) to try it out and if you're ready.
