Look into ketotifen for this (prevention of tolerance to clen). Benadryl was promoted to have this effect for a short time a few years ago but it was found not to be effective. Ketotifen has always been known to be effective at this but availability used to be an issue. Because ketotifen and benadryl both belong to the same class of antihistamines someone did a write up trying to make the contention that it would work the same as ketotifen when it came to preventing a tolerance build up in the b2 receptor, but it turns out that assumption was incorrect. Ketotifen can be had at rc companies easily now aa days as well and is cheap (like $20). rui has it.
good info. so benedryl isn't effective at all for this purpose or just not as good as keto?
