brother, you could get a ton of different answers here because everyone is completely different... some people have bad reactions, some allergic etc... you just have to do whats best for you... if one is giving you trouble, then you just have to try others until something works... i guess ive never had an issue with any of them but thats clearly not going to be helpful to you because you have already had issues... its just tough because what works for one could have no bearing whatsoever on you
