I barely got anything from Evorel or estradot patches and gave them up as I don't seem to absorb much from them.
However, even with only mildly good effects, those effects went away on day 4 of wearing a patch, in hot weather it could be day 3.
It's not meant to be worn longer than 4 days, but I found even on day 4 I could feel it was missing something.
Anxiety would be a prime candidate as a returning symptom.
As for applying patches, yes, half an hour max and that patch will have sorted you out if it's going to work at all, I find that amazing!
With other patches, Buprenorphine especially you can feel washing through your body and I'd soon be in withdrawal without it, but nicotine patches, sleep patches, travel sickness patches, I found all those excellent too.
I've had so many different patches, they definitely work in general, for a long time it was my preferred ROA for any medicine.
The only ones didn't work were the HRT patches!
I realised this nauseous, sweaty feeling can't be the desired effect of HRT and switched to Oestrogel. Now I know what the desired effect is. No more nausea, no more sweating.
