Hi fionajay77, I had a hysterectomy and I started on estrogel but changed to patches after a year but I had awful lightheaded feelings on both everol and estradot patches, I felt exactly like you drunk and wobbly also felt as though I couldn't walk straight like I was swaying I went back to gel and the intense lightheaded feeling went, I do still get it now and again not sure if it's just a menopause symptom or side effects from estrogen I never had the issue before starting hrt, estradot patches were the absolute worse for me the whole 3 months on that my head was spacey and floaty, I also think it can be from low estrogen or too much which I know isn't much help it's very confusing separating the too much too little issue, I'm much better on estrogel though and the patches for me personally was the cause of it being so intense, 50 patch is the same dose as 2 x pumps so I doubt it was too much as your dose wasn't increased , probably a side effect, if it goes once you are settled back on the gel you will know it was the patches, good luck I hope you settle back on the gel x
